A boy with a mass of 30 kg stands motionless at the end of a diving board 3 m above the floor. The boy has:
kinetic energy only.
potential energy only.

Potential energy, as the boy is not in motion and is suspended above the ground.
If you wanted to find the energy, the equation is;
PE = mgh
PE = 30 x 9.8 x 3
PE = 882J
