A light rope is attached to a block with mass 400 kg that, Ask an Expert

Academics

A light rope is attached to a block with mass 4.00 kg that rests on a frictionless horizontal surface. The horizontal rope passes over a frictionless, massless pulley, and a block with a mass m is suspended from the other end. When the blocks are released the tension in the rope is 10.0 N.

a) Draw two free-body diagrams, one for the 4.00-kg block and one for the block with mass m.

b) What is the acceleration of the blocks?

c) Find the mass m of the hanging block?

d) How does the tension compare to the weight of the hanging block ?
