Question

Please help !! A diver of mass 101 jumps upward off a diving board and into the water the diving board is 6m above the water

A when the diver jumps she has a speed of 1.2m/s how much kinetic energy does she have?

B how much gravational energy will she have gained at her highest point? Explain how you found your answer

C based on divers speed from part (a) how high above the board will she rise?

D how fast will the diver be moving when she hits the water?

Answer 1

A) use Ek = 1/2 mv^2 to find the kinetic energy the diver has
B) what will have happened to the divers kinetic energy when she comes to a stop?
C) use a kinematic equation to find her x(final) given that you know her v(initial), a and can work out the
D) similarly, use a kinematic equation to find her v(final) given that you know her v(initial), x(initial), x (final) and acceleration
