How is mechanical energy conserved when a ball is thrown?

WebAt maximum height, (the final position) the kinetic energy is. Kf = ½ mvf2 = ½ (1. 50 kg) (16. 6 m/s) 2 = 206 J. In this problem there are only conservative forces (namely, gravity). The mechanical energy is conserved: Ki + Ui = Kf + Uf. We already found the initial kinetic energy of the snowball: Ki = 300 J.
