Full solution with all the steps.

9. A projectile is fired with an initial speed of 120 m/s at an angle of 55.0 above the horizontal from the top of a cliff 50.0 m high. Find (a) The time taken to reach maximum height [10.0 s] (b) The maximum height with respect to the ground next to the cliff [542 m] (c) The total time in the air [20.5 s] (d) The range [1.41 km] (e) The components of the final velocity just before the projectile hits the ground [Horizontal Component = 68.8 m/s; Vertical Component = -103 m/s]
