Question

A golf ball is hit east down a fairway with an initial speed of 56 m/s at an initial angle of 25 (from a tee of negligible height). A crosswind blowing to the south produces an acceleration of the ball of-0.8 m/s2 a How long is the ball in the air and where does it land relative to the tee b) What is the maximum height of the ball c) Does it reach the putting green which is 325 m from directly east from the tee? If not at what angle(s) should the ball be hit to reach the green (assume no crosswind at this point)
