Question: One type of BB gun uses a spring-driven plunger to blow the BB from its barrel.
(a) Calculate the force constant of its plunger's spring if you must compress it 0.130 m to drive the 0.0580-kg plunger to a top speed of 25.0 m/s. N/m
(b) What force must be exerted to compress the spring? (Enter the magnitude.) N
