A certain type of pellet gun uses a spring-driven plunger to fire the BB from its barrel.
A) Calculate the force constant, in newtons per meter, of the plunger's spring if you must compress it 0.075 m to drive the 0.05kg BB to a top speed of 15 m/s.
B) What force must be exerted to compress the spring, in newtons?
