A projectile is launched from the top of a cliff, with an initial velocity of 52.5 m/s directed at an angle 41.35° above the horizontal; the cliff rim stands 121 m above the ground below (see figure). The projectile hits the ground below at point P, a distance X away from the base of the cliff.
(a) Determine the time of flight, that is, the interval between launch and impact.
(b) At the instant of impact, find the projectile's vertical and horizontal components of velocity.
(c) What is the maximum height reached by the projectile?
