A rock is thrown horizontally with a speed of 19 m/s from a vertical cliff of height 30 m.
(a) How long does it take to reach the horizontal ground below?
s
(b) How far will it land from the base of the cliff?
m
(c) What is the velocity (magnitude and direction counterclockwise from the +x-axis, which is the initial horizontal direction in which the rock was thrown) of the rock just before it hits the ground?
Magnitude m/s
Direction °
