Question

suppose that you drop the ball from a height of about 2m above the floor, releasing it from rest. on the axes that follow, sketch your predictions for the velocity-time and acceleration-time graphs of the ball's motion. assume that the positive y direction is upward

Answer 1

h = Vo*t + 0.5g*t^2 = 2 m.
0 + 4.9*t^2 = 2
t^2 = 0.4082
t = 0.639 s. = Fall time.

V = Vo + g*t = g*t. g = 10 m/s^2
Use the following points for graphing.
(t,v) = (0,0), (0.2,2), (0.3,3),(0.5,5),
(0.6,6).
