⚠️Our tutors found the solution shown to be helpful for the problem you're searching for. We don't have the exact solution yet.
A mass m is attached to a spring which is held stretched a distance by a force F and then released. The spring compresses, pulling the mass.
Assuming there is no friction, determine the speed of the mass m when the spring returns to its normal length ( x = 0 ).
Determine the speed of the mass m when the spring returns to half its original extension (x/2).
