Transcribed Image Text:

A projectile is launched with an initial speed of vo = 42 m/s from the top of a tall cliff (H = 100 m) at an angle = 25 below the horizontal (see Figure 11.3). A wall of height h is located a distance d = 90 m from the base of the cliff. The projectile just clears the top of the wall. How high is the wall? Neglect the effects of air resistance.
