a. How does the landing point depend on the position of the wall ?[br] the initial ↑ velocity ?, the initial → velocity ?[br][br]b. Sketch y(t) and x(t) for the case of a ball bouncing off the wall.[br][br]c. Sketch horizontal and vertical components of velocity as functions of time for the case of a ball bouncing off the wall.[br][br]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?[br][br]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?[br]Do you think it is OK to use this model of a ball bouncing off a wall? why or why not?
