A projectile is fired from the edge of a cliff as shown in the figure at an angle of 30 above the horizontal. The cliff is 20m high. The initial velocity is 24.32. The projectile reaches maximum height at point P and then falls and strikes the ground at point Q. How high is point P above point Q (in m)? Neglect air resistance and use g = 9.81m as the $2 magnitude of the acceleration due to gravity. 30 20m
