Solve the all parts of given problem:
Problem: 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?
I don't know how to get that answer for the above problem. Please help! Thank you.
