A golfer hits a ball with an angle of 53 degrees at a velocity of 50m/s. The horizontal component of the velocity is 30m/s and the vertical component of the velocity is 40m/s. Unfortunately she hits too hard and it JUST goes over the edge of the cliff and lands on the beach below. Draw a sketch of the situation to assist your reasoning (no need to submit the sketch) a) For how many seconds does the ball travel upwards (i.e. until it reaches the highest point)? b) What is the downward component of the ball’s velocity when it disappears from her view? c) How far away from the golfer is the ball when it disappears from her view?

d) If the ball falls over the cliff for another 4 seconds before reaching the beach, how high is the cliff?
