Question

The drawing shows a person who, starting from rest at the top of a cliff, swings down at the end of a rope, releases it, and falls into the water below. There are two paths by which the person can enter the water. Suppose he enters the water at a speed of 19.2 m/s via path 1. How fast is he moving on path 2 when he releases the rope at a height of 2.45 m above the water? Ignore the effects of air resistance.
