KE = ½mVi² - m*g*h = .5*.0462*51² - .0462*9.8*21.2 = 50.......
A 46.2-g golf ball is driven from the tee with an initial speed of 51.0 m/s and rises to a height of 21.2 m. (a) Neglect air resistance and determine the kinetic energy of the ball at its highest point.

It is not 0.

KE = KEi - PE
KE = ½mVi² - m*g*h = .5*.0462*51² - .0462*9.8*21.2 = 50.48 J
