Question

SHE-2 A horizontal spring-mass system is shown below. The mass slides on a frictionless surface. unloaded position is at xstxm, what fraotion of the total energy is potential-energy?" a) when the block words, tind UE/ET. the elastic Inother en the block is at x o, what fraotion of the total energy Is the elastio potentia n other words, find UE/ET c) when che block is at x--Ха, what fraction of the total energy is he elastic potential-energy?--Inother words, tind UE/Er. is the elastic potential energy? In other words, find UE/ET hen the blook is at x +xn/2, what fraotion of the total energy at x=+xm/2, what fraotion of the total energy e) When the blook is is the kinetic onergy? In other words, find E/Er r) When the block is at xn-3xa/4, what fraction of the total energy is the elastio potential energy? In other words, find E/ET g) When the blook is at xa-3xm/4, what fraotion of the total energy is the kinetic energy? In other words, find Ek/Er nt The mass slides
