Solve the all given part of following question:
Question: A toy gun can shoot 12.00-g plastic bullets at 6.00 m/s.
Part A: If the spring in the gun can be compressed by 5.00 cm, what is its spring constant?
Part B: What compression should be if the speed of the bullet is to be increased to 7.00 m/s?
Please show all work and steps clearly to find the spring constant. Thanks.
