In the high jump, Fran's kinetic energy is transformed into gravitational potential energy without the aid of a pole.

With what minimum speed must Fran leave the ground in order to lift her center of mass 1.95 m and cross the bar with a speed of 0.70 m/s?
Answered by drwls
Her initial kinetic energy must be greater than her kinetic energy at the top, by an amount equal to m g H, where H = 1.95 m.

The m's cancel out when you write the kinetic energy terms.
