current is 9/60 amps
power= I^2 r= (9/60)^2*10
A spring gun is made by compressing a spring (assumed to be perfect) and latching it. A spring of constant k = 60 N/ m is used and the latch is located at a distance of 7 cm from equilibrium. The pellets have mass 4 g. What is the muzzle velocity of the gun?
