Explanation:

To solve for the mass of the football player, we can use the conservation of momentum principle, which states that the total momentum before a collision is equal to the total momentum after the collision. Assuming the collision is perfectly elastic, we have:

m1 * v1 + m2 * v2 = m1 * v1' + m2 * v2'

where m1 is the mass of the football player, v1 is the initial velocity of the football player, m2 is the mass of the referee, v2 is the initial velocity of the referee, v1' is the final velocity of the football player, and v2' is the final velocity of the referee.

Since the referee is at rest before the collision, we can set v2 = 0. Plugging in the given values, we get:

m1 * 8 + m2 * 0 = m1 * (-8) + m2 * 5

Expanding and solving for m1:

8m1 = -8m1 + 80

16m1 = 80

m1 = 5 kg

So, the mass of the football player is 5 kg.

At approximately 2.81 seconds the cars are at the same point. aA(t) is a linear function and xB(t) is a parabolic function.

Functions aA(t) and xB(t) describes the motion of two cars and both functions give the distance of each car from the starting point as a function of time, t.

aA(t) is a linear function and the components of the functions are constant velocity (p) and acceleration (q).

xB(t) is a parabolic function with components constant acceleration (r) and a component for constant jrk (s).

To find the time when the two cars are at the same location, we must first make the two distance expressions equal and then solve for t.

That is pt + qt² = rt² - st³

Now we have to solve this for t, we get

t = (-p + (p² + 4qr)^1/2) / (2q)

Now add the values for p,q,r,s to solve the equation

t = (-2.6 + (2.6² + 4 × 1.2 × 2.8)^0.5) / (2 × 1.2) = approximately 2.81 seconds.

The orbital period of this asteroid is approximately 353.55 Earth years.

Kepler's third law states that the square of the orbital period (in years) of a planet or asteroid is proportional to the cube of its semi-major axis (in AU).

Therefore, we can use the following formula to calculate the orbital period:

(T / 1 year)^2 = (a / 1 AU)^3

where;

Plugging in the values for the asteroid at 50 AU, we get:

(T / 1 year)^2 = (50 / 1 AU)^3

(T / 1 year)^2 = 125000

T / 1 year = √(125000)

The velocity of car 2, from the frame of reference of car 1, is 20 m/s west. (Answer: B)

When considering the frame of reference of car 1, we need to subtract the velocity of car 1 from the velocity of car 2 to determine the relative velocity. Since car 1 is moving at 45 m/s west and car 2 is moving at 25 m/s east, we can subtract these velocities to find the relative velocity of car 2 with respect to car 1.

45 m/s (west) - 25 m/s (east) = 20 m/s (west)

Therefore, car 2 has a velocity of 20 m/s west when observed from the frame of reference of car 1. It is important to note that velocities are vector quantities, which means they have both magnitude and direction. In this case, the direction is west because car 2 is moving in the opposite direction of car 1. (Answer: B)

define mass ?

The density and kind of atoms in any specific thing are referred to as the object's mass in science. Although mass can also be measured in pounds, the kilogramme (kg) is the SI unit of mass (lb).

Think of a pillowcase stuffed with feathers and one packed with bricks to rapidly grasp the notion of mass. Which one is heavier? The bricks have a larger mass because their atoms are heavier and denser. Because of this, although though both pillowcases are the same size and level of fill, one has a significantly higher mass than the other.

In this case, the mass is denoted by (m), while the distance is denoted by (x).

The 3.9m-long log weighs 260kg and is long. Burt weighs 30 kg, whereas Ernie weighs 40.5 kg.

Ernie accepts Burt's offer of a cookie and moves to his side of the log to take it.

By the time Ernie gets to Burt, the log should have travelled x metres. Consequently, using the formula above,

Answer:

pH2S = 0.816 atm

pH2 =  0.0153  atm

pS2 = 0.00765 atm

Explanation:

Step 1: Data given

Kp = 2.2 *10 ^-6

Initial pressure H2S = 0.824 atm

Step 2: The equation

H2S(g) ⇌ 2H2(g) + S2(g)

Step 3: The initial pressure

pH2S = 0.824 atm

pH2 = 0 atm

pS2 = 0 atm

Step 4: The pressure at the equilibrium

pH2S = 0.824 - x atm

pH2 = 2x atm

pS2 = x atm

Kp = ((pH2)² * (pS2))/pH2S

2.2 * 10^-6  = ((2x)² * x) / (0.824 - x)

2.2*10^-6 = 4x³ / (0.824 - x)

4x³ = 2.2*10^-6 * (0.824 - x)

x = 0.00765

pH2S = 0.824 - 0.00765 = 0.816 atm

pH2 = 2* 0.00765 = 0.0153  atm

pS2 = 0.00765 atm

The change is small enough to be neglected because 0.00765 << 0.824

If we calculate the result with or without this change the result will not be very different

2.2*10^-6 = 4x³ / (0.824 )

x = 0.00768 atm

pH2S = 0.824 - 0.00768 = 0.816 atm

pH2 = 2* 0.00768 = 0.0154  atm

pS2 = 0.00768 atm

-240

Explanation:

A motorcycle skids for a distance of 2.0 m on an icy road, then the change in kinetic energy for the motorcycle will be equal to -240 J.

The force which a moving object has is referred to as kinetic energy in physics. It is defined as the number of effort required to propel a person of a specific mass from still to a specific velocity.

Aside from slight fluctuations in speed, your body holds onto the kinetic energy it obtains during acceleration.

When the body slows down from its present level to a condition of rest, the same quantity of energy is used.

Formally, kinetic energy is any quantity that has a gradient concerning time in the Lagrangian of a system.

As per the given information in the question,

Distance, d = 2.0 m

Friction, f = 120 N

The angle between displacement and friction force, θ = 180°

Now, the change in kinetic energy for the motorcycle = Work done by the friction.

K.E = f × d(cos θ)

8.33 m/s² quickly would a 60kg object accelerate if the person applied a 500N force.

Acceleration the rate at which speed and direction of a moving object vary over time. A point or object moving straight ahead is accelerated whenever it accelerates or decelerates. Even if the speed remains constant, motion on the a circle accelerates so because direction is constantly shifting.

An item that is slowing down will always have a negative acceleration if the current direction of motion is constantly selected as positive.

Force = mass × acceleration

Answer:

-The wave will be reflected but inverted

Explanation:

This is a transverse wave because the wave is moving to the right and the particles are moving up and down. When a transverse wave reaches the end, it is reflected and inverted so the crest becomes through and the through becomes valleys. So, the answer is

-The wave will be reflected but inverted.

Because when a wave finds a fixed end, the wave is reflected, which means that there will be a wave with the same speed and amplitude but in the opposite direction.
