Probably really easy

    A block of mass m1 = 280 g is at rest on a plane that makes an angle = 30° above the horizontal (Figure 5-41). The coefficient of kinetic friction between the block and the plane is µk = 0.1. The block is attached to a second block of mass m2 = 210 g that hangs freely by a string that passes over a frictionless and massless pulley. When the second block has fallen 30 cm, its speed is?

    How do I solve this

    Hint: find the tension in the string caused by the motion of block 1.
