No credit will be awarded for an answer without your showing or explaining how you got it. be as clear as possible: legibility will only tick off the grader. (this is not a good idea.) 1 pt xc on this pset if you demonstrate successfully to me that you have at least checked answers with another student; 2 pts xc if you demonstrate that you have done so intelligently do not forget your labels you are playing tennis. the ball comes toward you. when it is a height h above the ground you hit it towards the net at an angle of ф above the horizontal, at a speed of vo. the net is height h, and a distance d away. we want to figure out if it will clear the net. do not put in numbers until part d. no numbers without units a. (4 pts) draw a complete motion map for the ball (leave out the net) with time beginning at the point just before you hit the ball. use x as the axis defined by the two points (ball hit) and (net), and y as the vertical axis b. (12 pts) draw (approximate) graphs of x, v., a,, y, v,, and a, (6 graphs), as functions of time. write next to each graph an equation that represents each function c. (2 pts) in terms of the given variables, find the time at which the ball reaches the net, and the height of the ball at that time. d. (2 pts) suppose that h 1.0 m, ф-15°, vo 13 m/s, h-1.5 m, and d-5.0 m. does the ball clear the net? (now you can put in numbers.) e. (xc! 2 pts poss.) what is its velocity (not speed) when it reaches the net? is it past its highest point, at its highest point, or yet to reach its highest point?
