In the high jump, the kinetic energy of an athlete is transformed into gravitational potential energy without the aid of a pole. With what minimum speed must the athlete leave the ground in order to lift his center of mass 2.00 m and cross the bar with a speed of 0.670 m/s?© BrainMass Inc. brainmass.com March 4, 2021, 5:46 pm ad1c9bdddf
By law of conservation of energy:
initial kinetic energy at ground = final potential ...
With explanation and calculations, the problem is solved.
