At a state fair a strongman claims to be able to throw a m=100 g baseball straight up in the air (ignore air resistance) with an initial speed of 40 m/s. You decide to test his claim by computing a few simple things that you can observe.
A) At what time should the baseball be moving at 20 m/s upward?
B) At what time should be be moving at 20 m/s downward?
C) When does it return to the height from where he threw it again (assume the ball starts at ground level...not exactly true, but close enough).
D) When does it reach its highest point?
E) What is the acceleration of the ball as it is moving upward? Downward?
F) Make Matlab graphs of the acceleration versus time, velocity versus time, and position versus time for the ball. Turn in plots and copies of your Matlab code. can you show all steps.
