CH15. A block and spring system oscillating in SHM has a maximum speed of 1.24 m/s and a total energy of 1.71 J. What is the mass of the block?

CH15. A block and spring system oscillating in SHM has a maximum speed of 1.24 m/s and a total energy of 1.71 J. What is the mass of the block?
Solution: At maximum velocity, the spring would have no force exerted on theblock, meaning that the potential energy stored in the spring would be 0.HENCE,
