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.
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?
