10. What is the velocity at 2.0s ? Show your workings. [Use the appropriate equationsdetermined in question 1.]11. What is the ball’s vertical and horizontal position at 2.0s ? Show your workings. [Use theappropriate equations determined in question 1.]12. A golfer on Gros Morne drives golf balls off the peak at 14.0 m/s @ 20° above thehorizontal. If the peak is 800m above the bottom of the Fjord on the north side of themountain, then determine the ball’s:a) time of flightb) horizontal rangec) maximum altitude of the ball (relative to the Fjord)d) impact velocity13. A ping pong ball bounces off a table, 0.85m above the ground. If the ball strikes the floorat 5.44 m/s @ 56.5° below the horizontal, then determine the ball’s:a) initial velocityb) time of flightc) horizontal ranged) maximum height relative to the floor- 17 -
