Problem 3:   Consider a projectile launched with an initially horizontal velocity of 19.7m from a cliff of height h=9.23m. It travels a horizontal distance, d, before striking the ground at an angle θ below the horizontal. Use the Cartesian coordinate system provided in the drawing with the origin at the base of the cliff. Assume that air resistance is negligible.    Part (a)  How much time elapses, in seconds, from the moment the projectile is launched until it strikes the ground?   Part (b)  What is the horizontal distance, in meters, traveled by the projectile?  Part (c)  What is the speed of the projectile, in meters per second, as it strikes the ground? Part (d)  What is the impact angle, in degrees below the horizontal, at which the projectile strikes the ground?
