Question

Dana has set up a target for her toy spring gun. The gun requires 5.50 g pellets as ammunition that travel 11.4 m/s when shot. If the spring inside has maximum compression of 0.0700 m, what is the spring constant for the spring in the toy gun?

Answer 1

(1/2) k x^2 = (1/2) m v^2

k (.07)^2 = .0055 (11.4)^2
