A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of 21.0 m/s. The cliff is h = 60.0 m above a flat horizontal beach.
A)How long after being released does the stone strike the beach below the cliff?
B)With what speed and angle of impact does the stone land?

how long does it take to fall 60m?
h=1/2 g t^2
vf=g t
then, for the speed, combine horizontal speed with the vertical speed as vectors.
