and m1 is almost about to slip up the incline. The pulley is
“ideal” and the string supporting m2 has a length of 3.0 meters.
Each mass rotates in a horizontal circle, but with different
r-values, one of which is given. Draw a clear force diagram for
each mass, write down the appropriate force equations, and solve
them to find the tension (T) in the string, the normal force...

A common question in physics, which often arises is the question about whether a friction force, f, does work. If a block is sliding down a rough surface with kinetic coefficient of friction, Mu_k. Carefully reflect on discussions held in class, and then, pick the correct statement about whether the force of friction actually does work on the block, as the block slides down the plane. Select one: a. Work done by friction is equal to zero. b. Work done...
