A 45.7-g golf ball is driven from the tee with an initial speed of 46.0 m/s and rises to a height of 25.9 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 6.82 m below its highest point?

    Kinetic Energy at any point= 1/2 m 46^2-mgh

    put in h, and solve.

    for b, h= 25.6-6.82
