The trick to skipping a rock is throwing it at a low angle. This is because the surface tension of the water can only provide so much force, beyond which the rock goes into the water instead of bouncing off its surface. You throw a rock of mass m = 0.05 kg with a speed of vo = 20 m/s. The surface tension of the water can provide a maximum force of F5 N. The collision of the rock with the water lasts At = 0.1s. Assume it bounces off the water at the same angle and speed it collided with. Find the maximum angle (measured from horizontal) at which you can throw the rock and still have it skip off the surface. You can ignore gravity.

A tennis ball is flying eastward towards a wall with a speed of 33.7 m/s. After bouncing against the wall, it's flying westward with a speed of 21.9 m/s. If the mass of the ball is 0.1 kg, and the time the tennis ball is in contact with the wall is 0.032 s, what is the magnitude of the force in N the ball exerts on the wall?
Kaya, a crew member on an interplanetary space ship, is on a spacewalk. She realizes that her ship is moving away from her at 0.5 m/s. She and her spacesuit have a total mass of 95 kg. Her space suit includes a 15 kg backpack, which is included in the 95 kg total mass.a). What is the minimum velocity she will have to throw the backpack so that she can gain enough velocity to eventually catch up with the ship? b). Kaya applies an average force of 400 N to the backpack for 0.05 seconds. Will Kaya make it back to the ship? If so, determine how much time it will take for her to reach the ship. If not, determine how much more force she would need to apply to make it back.
