An olympic gymnast jumps up and down on a trampoline. If the gymnast's feet leave the trampoline at a height of 1.0 m above the ground and reach a maximum height of 6.0 m above the ground, at what speed was the gymnast launched from the trampoline?

Step 1

According to the principle of conservation of energy, the sum of the change in potential energy of the gymnast and the change in his kinetic energy will be equal to zero.

Step 2

Put equations (2) and (3)...
