The blocks ov mass m_(1)=1kg and m_(2)=2kg are connected by an ideal spring, rest on a rough horizontal surface. The spring is unstressed. The spring constant of spring is K=2N//m . The coefficient of friction between blocks and horizontal surface is mu=(1)/(2) . Now the left block is imparted a velocity u towards right as shown. The largest value of u( in m//s) such that the block of mass m_(2) never moves is ( Take g=10m//s^(2))
