QUESTION 1 A ball is thrown vertically upward with an initial speed of 14.0 m/s. Neglect air resistance. a) Find the ball's maximum height above its release point. (3 marks) bj Determine the time taken for the ball takes to reach its maximum height. (2 marks) C) Show that there are two possible times for the ball to reach a point 3.0 m above its release point. Explain why there are two answers. (5 marks) dj Determine the time taken for the ball to reach its maximum height if the ball is thrown at an angle of 30" above the horizontal with the same initial speed. Compare your answer to part (b). (5 marks) QUESTION 2 a) Define weight. (2 marks) b) Two objects of mass m, = 2 kg and my = 5 kg are connected by a light string and hung over a frictionless pulley as shown in Figure 1. Both objects are released from rest. Assume both string and pulley has negligible mass. I) Draw a free body diagram for each object. (2 marks) i) Calculate the acceleration of the objects. (5 marks) iii) Calculate the tension on the string. (3 marks) c) A force 12 N, acting on an object produces an acceleration of 5 m/s. If the mass is doubled, find the magnitude of force to produce an acceleration of 7 m/s
