Homework Answers
u = 36 m/s
v = 0 m/s (since at the highest point, velocity is zero)
Use:
v^2 = u^2 – 2gS
=> S = (u^2 – v^2)/2g
= (36^2 – 0)/(2*9.8)
= 66.1 m

A 2.7-kg ball is thrown upward with an initial speed of 20.0 m/s from the edge of a 45.0 m high cliff. At the instant the ball is thrown, a woman starts running away from the base of the cliff with a constant speed of 6.00 m/s. The woman runs in a straight line on level ground, and air resistance acting on the ball can be ignored. 1.At what angle above the horizontal should the ball be thrown so that...
