A block of mass m = 2 kg is attached to a spring with spring constant k = 200
N/m, and is set to oscillate on a friction-less horizontal surface. At time t = 0 its
position is X0 = 0 and its velocity is v0 = +5 m/s. If the displacement is a cosine
function, X(t)=A cos(wt+p), then which answer is correct about the oscillation
amplitude A and the phase constant, p.:

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
