A baseball is hit vertically upward and is caught by the catcher 2.68s later. Assume the ball was hit and caught at a height of 1.00m.
what is the velocity of the ball when it is hit off the bat?
what is the balls maximum displacement?

Tr = 2.68/2 = 1.34 s. = Rise time.
V = Vo + g*Tr = 0 @ max. ht.
Vo = -(g*Tr) = -(-9.8*1.34) = 13.13 m/s.
D = h - ho = 1m - 1m = 0
V = Vo + g*Tr = 0 @ max. ht.
Vo = -(g*Tr) = -(-9.8*1.34) = 13.13 m/s.
D = h - ho = 1m - 1m = 0
