A62 kg rock climber falls off the wall at the gym. immediately before she hits the padded floor, her velocity is 7.9 m/s, 15° away from the vertical. she comes to a stop 0.75 s later. what vertical force did the padded floor exert on the rock climber? if the floor was not padded and she instead came to a stop in 0.25 seconds, what vertical force would the floor have exerted on her?

Explanation:

Given

mass of climber= 62 kg

velocity of climber before it hits=7.9 m/s at an angle of from vertical

therefore change in momentum in vertical direction is

there is no change in horizontal momentum

and impulse=change in momentum

F.dt=946.22

For non padded floor

concave lenses are used here. they spread the light out before it reaches the convex lens in the eye, therefore letting the image focus directly on the retina. hyperopia is known to you probably as farsightedness.
