Problem 5) A spring-loaded cannon is often used during projectile motion or conservation of energy physics labs. Suppose you place a 3.47x10-³ kg steel ball into the cannon. The cannon is pointed straight up, the ball is placed into the cannon, and you compress the spring by 0.091 m using a stick. a) Calculate the work done by gravity as you compress the spring. b) Suppose the spring has a spring constant of 8.42 N/m. Calculate the work done by the spring as it is compressed. c) Suppose the spring is now released and the ball rises with the spring. Calculate the net work done on the ball when the spring reaches its uncompressed position (its equilibrium position). d) The ball was initially at rest. Calculate its speed given at the position described in part (c).
