A diver of mass 50-kg jumps from a cliff at 5.00m/s upward at an angle of 30o as measured from the horizontal surface of the cliff. The cliff is 20 m above the surface of a body of water. (Friction is negligible)

Determine

a) the final velocity of the diver just before the diver strikes the body of water using Projectile Motion Kinematics

b) the magnitude of the final velocity of the diver just before the diver strikes the body of water using Conservation of Mechanical Energy,

c) the maximum height, as measured from the surface of the body of water, using Conservation of Mechanical Energy.
