Physics 12 Mid-Year Review
10. A 0.060 kg steel ball is pushed 0.080 m down a launching tube against a spring. The force exerted by the spring increases from zero to 400 N as the ball is pushed down the tube, as shown in the graph below. (Assume no energy losses due to heat)
a) The ball is then released. What is the speed of the ball as it leaves the tube?(3 marks)
b) What is the range, R, of the ball?
