Question

Please only use the following kinematic equations:

v=vnot+at

x=xnot+vnot(t)+1/2at^2

v^2=vnot^2+2a(deltax)

(deltax)=(v+vnot/2)(t)

A baseball player throws a 550.-gram ball straight up with an initial velocity of 28.0 m/s. (ignore air resistance)

a) Find maximum height reached by the ball.

b) At what time (after ball is thrown) does the ball return past its starting position?

c) Find the ball's displacement and velocity 3.70s after the ball is thrown. Specify whether the velocity is upward or downward.
