PLEASE SHOW ALL THE STEPS

1. A 1kg ball is moving at 5 m/s. This ball strikes a stationary identical ball. If the first ball rolls backwards at 2 m/s, then what is the speed of the stationary ball after the collision.

2. A force of 15.0 N acting at an angle of 25.0 deg to the horizontal is used to pull a box a distance of 5.00 m. How much work is done?

3. A 3.5 kg block sliding at 10 m/s comes into contact with a 40-deg incline. If the coefficient of friction is 0.35, how far up the ramp will the block go? (hint: trig substitution is needed)

4. I kick a 100 g stationary ball with 500 N of force and have contact with the ball for 2.0 ms. What is the speed of the ball after it is kicked?
