A 50.3g golf ball is driven from the tee with an initial speed of 57.0 m/s and rises to a height of 33.2 m. (a) Neglect air resistance and determine the kinetic energy of the ball at its highest point. (b) What is its speed when it is 7.04 m below its highest point?

KE=initial KEmgh

Kristi,
How do I figure out the speed then?

bobpursley,
ke final=1/2 m vf^2
initial KE= 1/2 m vi^2
