    Two blocks A and B are connected to each other by a string and a spring, the string passes over a frictionless pulley as shwon in figure. Block B slides over the horizontal top surface of a stationary block C and block A slides along the vertical side of C, both with the same uniform speed. The coefficient of friction between the surfaces of blocks is 0.2. Force constant of the spring is 1960 N/m. If mass of block A is 2 kg calculate the mass of block B and the energy stored in the spring.
