A spring is compressed between two blocks of masses m1andm2m_1 and m_2 placed on a horizontal frictionless surface as shown in the figure. When the blocks are released, they have initial velocity of v1andv2v_1 and v_2 as shown. The blocks travel distances x1andx2x_1 and x_2 respectively before coming to rest. The ratio (x1x2)\left(\frac{x_1}{x_2}\right) is A spring is compressed between two blocks of masses m_1 and m_2 placed on a horizontal frictionless surface as shown in
