Oct 09, 2012 · A block of mass m1 = 3.70 kg on a frictionless inclined plane of angle 30º is connected by a cord over a massless, frictionless pulley to a second block of mass m2 = 2.30 kg hanging vertically ...

If the mass on the incline is large enough, it will overcome friction and move downward, pulling the hanging mass upward. In this case the friction force will act up the incline. There is an intermediate range of masses where the block will move neither up nor down the incline. Application of Newton's second law to mass on incline with pulley.

An object of mass m= 4:0 kg, starting from rest, slides down an inclined plane of length l= 3:0 m. The plane is inclined by an angle of = 30 to the ground. The coe cient of kinetic friction k = 0:2. At the bottom of the plane, the mass slides along a rough surface with a coe cient of kinetic friction k = 0:3 until it comes to rest. The goal of this problem is to nd out how far the object slides along the rough surface.

2. A pulley of mass ml=M and radius R is mounted on frictionless bearings about a fixed axis through O. A block of equal mass m2=M, suspended by a cord wrapped around the pulley as shown above, is released at time t = 0. The acceleration of the block is measured to be (2/3)g in an experiment using a computer-controlled motion sensor. a.
