A 49g golf ball is hit from rest using a golf club at an angle of 0= 35 degrees and reaches a horizontal distance of 171m. Assume negligible air resistance therefore only gravitational acceleration. I) Determine the how long the club is contact with the ball if the force exerted on the ball is 0.3kN. Hint: use projectile motion in both directions. [6] I) The golf ball hits another stationary golf ball of the same mass, determine the final velocities of the two balls if, the moving ball transfers 56% of its momentum to the stationary ball.[4]
