As shown in the figure below, a girl and a boy are playing dodgeball on a 37° slope. The initial distance between them is 3 m. The girl throws the ball with an initial horizontal velocity vo, and meanwhile, the boy begins running downhill at a constant velocity of 4 m/s. (Note: Neglect the dimensions of the boy and the girl and air resistance). a) Assuming that the ball hits the boy before he reaches the bottom of the slope, determine the time it takes for the ball to hit the boy. (10 marks) b) How far has the boy travelled until the ball hits him? (10 marks) What is the initial speed of the ball? (i.e. vo) (10 marks) Girl Vo 3 m Boy V=4 m/s 37
