A toy gun uses a spring with a force constant of 315 N/m to propel a 9.5-g steel ball. Assuming the spring is compressed 7 cm and friction is negligible, answer the following questions:
Randomized Variables
k = 315 N/mm = 9.5 gd1 = 7 cm
Part (a) What is the magnitude of the force, in newtons, that is needed to compress the spring?
Part (b) What is the maximum height, in meters, to which the ball can be shot?
Part (c) What is the gunA?1s maximum range, in meters, on level ground?
