two objects of masses 1 kg and 3 kg are held stationary on a frictionless surface with a compressed massless spring between them. when the blocks are released, the 1 kg object moves to the left with velocity 9 m/s. what is the velocity with which the 3kg object moves to the right.

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k
