A 45.9-g golf ball is driven from the tee with an initial speed of 47.4 m/s and rises to a height of 34.1 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 5.06 m below its highest point? 3% A 45.9-g golf ball is driven from the tee with an initial speed of 47.4 m/s and rises to a height of 34.1 m.
