Answer to Question #34237 in Mechanics | Relativity for Khanye
An athlete completes the flight phase of a standing vertical jump in 0.51 s. Assuming that his centre of mass landed at the same height that it took off from (i.e. the time taken to reach the apex of the jump was the same as the time taken to land from the apex).
a) what isThe take-off velocity of the athlete
(b) The height raised by the centre of mass during flight (i.e. displacement of the centre of mass between the time of take off and the apex of the jump
