A diver jumps vertically off a 10m platform, reaches a maximum height of 1.5m above the platform, and lands in a swimming pool below. Three seconds after entering the water, her downward motion is stopped. (a) What was her average acceleration in the water? (b) Sketch her position versus time, velocity versus time, and acceleration versus time. Check for consistency between the graphs and explain why your graphs are consistent.

A tennis ball is it at ground level. The ball reaches its maximum height above the ground level 1 sec. after being hit. Then 0.9 seconds after reaching its maximum height, the ball barely clears the net that is 3 m from where the tennis ball was hit. Assume the ground is level. How high is the net?  How far beyond the net does the tennis ball strike the ground?

  A rock is thrown upward from a bridge that is 83 feet above a road. The rock reaches its maximum height above the road 0.61 seconds after it is thrown and contacts the road 3.87 seconds after it was thrown. Write a function f that determines the rock's height above the road (in feet) in terms of the number of seconds tt since the rock was thrown. THE FUNCTION MUST BE IN THE FORMAT f(t)=c⋅(t−t_1)(t−t_2) for fixed numbers c,...
