Transcribed Image Text:

A child stands at the edge of a cliff of height h from the ground and throws a stone at an initial speed 20 m/s downwards at an angle of 60 from the vertical as shown. The rock strikes the ground 4.0 seconds later at a distance d from the bottom of the cliff. a) Find the components of the initial velocity (PAY ATTENTION to the location of the angle in the problem picture). b) Find the height, h, of the cliff.
