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?

Ineed with angles and the measure of them i have abc a is 65 and b is (3x-10) and c is (2x) find the value of x
