Chapter 3, Problem 24Q
(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) 24. Many sports involve collisions between things—such as balls and rackets—and between people—as in football or hockey. Characterize the various sports collisions as elastic or inelastic.

Please don't provide handwritten solution.
A 50 kg mass that weighs 490 Newtons is pushed up a 20m lone ramp that is 2m high. (h). The force required to push the block up the ramp is 49 Newtons. Assume the ramp is frictionless. Don’t confuse mass with weight. Weight is a force and is equal to mg.
Answer each question with your work.
Calculate the velocity of the block when it reaches the bottom of ramp. (mgh=1/2mv2)
If the block is drop from the top of the ramp and fall straight down to the ground,how much kinetic energy will it have at the moment it strikes the ground? Note: many students will answer zero. Keep in mind we are talking about the moment just before it hits the ground. (mgh=1/2mv2)
Calculate the velocity of the block the moment it strikes the ground. Keep in mind that it is still moving at that moment.
