a. How does the landing point depend on the position of the wall ?
the initial ↑ velocity ?, the initial → velocity ?
b. Sketch y(t) and x(t) for the case of a ball bouncing off the wall.
c. Sketch horizontal and vertical components of velocity as functions of time for the case of a ball bouncing off the wall.
d. What can you say about the relation between the angle at which the ball hits the wall and the angle at which it leaves the wall?
e. What happens at the wall? For how long is the ball in contact with the wall? Is your answer realistic? why or why not?
