Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

A diver springs upward from a diving board. At the instant she contacts the water,
her speed is 8.20 m/s, and her body is extended at an angle of 64.0° below the
horizontal. At this instant her vertical displacement is -2.10 m, where downward
is the negative direction. Determine the magnitude and direction of her initial
velocity immediately after leaving the diving board.

A ball is thrown from a rooftop with an initial downward velocity of magnitude v0=0.53m/s. The rooftop is a height h=37.2m above the ground. 1. Find the vertical component of the final velocity meters per second, with which the ball hits the ground. 2. If the height is fixed at 37.2m, but we wanted the ball's final speed to be 32.7m/s, what would the vertical component, in meters per second, of the initial velocity need to be?
