a block of mass 250 kg is at rest on a plane that makes a 30 angle with the horizontal. the coefficient of kinetic friction between the block and the plane is 0.100. The block is attached to a second mass m2=200 g that hangs freely by a string that passes over a frictionless, massless pulley. When the second block has fallen 30.0 cm, what will be its speed ?
