m 1 m 2 θ A block of mass m 1 rests on a rough inclined plane and is attached to a hanging mass of mass m 2 by a string which is draped over a frictionless, massless pulley. If the coefficient of kinetic friction between m 1 and the plane is μ k , how long will it take m 2 to fall 1.2 m to the floor? PHYS 2101 Spring 2011
