Consult conceptual example 9 in preparation for this problem. interactive learningware 6.3 also provides useful background. 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 13.4 m/s via path 1. how fast is he moving on path 2 when he releases the rope at a height of 2.34 m above the water? ignore the effects of air resistance.

11.56066 m/s

Explanation:

m = Mass of person

v = Velocity of person = 13.4 m/s

g = Acceleration due to gravity = 9.81 m/s²

v' = Velocity of the person in the second

The kinetic and potential energy will balance each other at the surface

Height of the cliff is 9.15188 m

Let height of the fall be h' = 2.34 m

The speed of the person is 11.56066 m/s

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
