With their centers vertically aligned, both balls are
released from rest at the same time, to fall through a
distance of 1.20 m. What are the velocities of the
tennis ball and basketball immediately before they
strike the floor (up = positive)?
A.
B.
C.
D.
vT = 4.85 m/s, vB= -4.85 m/s
vT = -4.85 m/s, vB= -4.85 m/s
vT = -4.85 m/s, vB= 4.85 m/s
vT = 4.85 m/s, vB= 4.85 m/s
½ m v2 = mgh Î v2 = 2gh independent of m
