Solve the problem.The optimal angle of elevation ? that a shot-putter should aim for in order to throw the greatest distance depends on the velocity v of the throw and the initial height h of the shot. One model for ? that achieves this maximum distance is ? = sin-1. Suppose a shot-putter can consistently release the steel ball with velocity of 40 feet per second from an initial height h of 5.7 feet. What angle, to the nearest degree, will maximize the distance?

A. 68° B. 46° C. 42° D. 64°
