[Solved] Mechanics Elastic potential problem Watch
I assume that the string is slack when it is at its natural length, is that right? I got the right answer when I consider the work done by gravity on the other direction. In which the total energy of the system when it's slack will be EPE/ converted to KE - Work done by gravity. But I thought wouldn't the total energy of the system be only Kinetic energy instead of Kinetic energy - work done by gravity. Because wouldn't gravitational potential energy would be 0 and only gained after the point of being slack. Please help!
