A toy gun uses a spring with a force constant of 300. N/m to propel a 10.0-g steel ball. If the spring
is compressed 7.00 cm and friction is negligible: (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?
