A91 kg football player catches a 0.700 kg ball with his feet off the ground with both of them moving horizontally. the player's speed is 5.30 m/s, and the ball's speed is 28.4 m/s. (a) first, consider the situation where the player and the ball are going in the same direction, and take this direction as positive. calculate their final velocity (in m/s). m/s (5 attempts remaining) input 1 status (b) calculate the change in the kinetic energy (in joules) of the system (of the player and the ball). δke

a) V = 5.47m/s

b)

Explanation:

Since the ball and the player become a whole system after the catch:

Solving for V:

The initial kinetic energy was:

The final kinetic energy was:

So, the change in the kinetic energy was:

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
