A light rope is attached to a block m, = 6.00kg that rests on a
frictionless, horizontal surface. The horizontal rope passes over a
frictionless, massless pulley, and a block with mass m, is suspended
from the other end. When the blocks are released, the tension in the
rope is 17.0N.

(b)
m2
Draw two free-body diagrams: one for each block.
What is the acceleration of either block?
Find m2.
How does the tension compare to the weight of the hanging block? Why?
(d)
A 4.00 kg block sits on a table top with a coefficient of static friction of 0.470 and a coefficient of kinetic friction of 0.320. A weight is attached by a string to the block so as to just overcome the force of static friction acting on the block. What is the acceleration of the block?Please give a step by step for the solution and a final answer.Thanks!!
