Ablock of mass m1 = 280 g is at rest on a plane that makes an angle θ = 30° above the horizontal. the coefficient of kinetic friction between the block and the plane is μk = 0.10. the block is attached to a second block of mass m2 = 200 g that hangs freely by a string that passes over a frictionless and massless pulley. find its speed when the second block has fallen 30.0 cm.
