A block of mass m1= 4.00 kg moves on the surface of a horizontal table. The coefficient of kinetic friction k between the table top and m1 is equal to 0.350. Block 2 of mass m2= 2.00 kg is tied to m1 via a string that passes over a frictionless, massless pulley. The two blocks start from rest and m2 drops by a distance L =1.75 m to the floor.
Use the work-energy theorem to determine the speed v of the blocks when m2 reaches the floor.
