Atoy gun uses a spring with a force constant of 285 n/m to propel a 9.5-g steel ball. assuming the spring is compressed 7.6 cm and friction is negligible, answer the following questions: (a) how much force is needed to compress the spring? (b) to what maximum height can the ball be shot? (c) at what angles above the horizontal may a child aim to hit a target 3.00 m away at the same height as the gun? (d) what is the gun's maximum range on level ground?
