A juggler tosses a 0.4kg ball straight up at 8m/s, and then catches it at the same height .
a. determine the acceleration on the way up and down
b. determine the total amount of time spent in the air by the ball. (hint: you know the displacement)
c.determine the velocity of the ball just as the juggle catches it. (Hint: it is not zero)
if this is on Earth, acceleration is -9.8m/s^2
hf=hi+vi*t-1/2 g t^2
or 8=4.8t solve for time t in air.
vf=vi-9.8t solve for vf
