If the phase angle for a block-spring system in SHM is π/8 rad and the block’s position is given x = xm cos(ωt + ?),what is the ratio of the kinetic energy to the potential energy at time t = 0?
What is the potential energy in terms of position? What is the speed under the stated conditions? What is the position under the stated conditions? What is the kinetic energy in terms of speed?
