A golf ball is projected with a speed of 35m/s at an elevation 35 relative to the horizontal.

Find:

(a) the greatest height reached by the golf ball (30%)

(b) the time of flight and horizontal range (30%)

(c) the speed and direction of motion at a height of 4m. What is the value of the corresponding horizontal position(s)?

g = 9.81 m/s^2
