A 64.1-kg athlete leaps straight up into the air from a trampoline with an initial speed of 7.4 m/s. The goal of this problem is to find the maximum height she attains and her speed at half maximum height.

Write the general equation for energy conservation and solve for the velocity at half the maximum height. Substitute and obtain a numerical answer.

Write a general equation for energy conservation in this case and solve for the maximum height. Substitute and obtain a numerical answer.
