In a pulley mass experiment, you have two blocks of masses M₁ and M₂ are connected with an
ideal string that passes over a massless and frictionless pulley. You noticed that after you
releases the system, M, mass accelerates rightward. Now your goal is to make the system
move with constant speed. Determine the mass of m that can be placed over M, with which the
system moves with constant speed. Assume the coefficient of friction between table and block
is μ.

A 1.5 kg block and a 2.5 kg block are attached to opposite ends of a light rope. The rope hangs over a solid, frictionless pulley that is 33 cm in diameter and has a mass of 0.75 kg. The pulley can be modeled as a cylinder. When the blocks are released, what is the acceleration of the lighter block? Express your answer in meters per second squared.
Your answer is partially correct.
In a two-dimensional tug-of-war, Alex, Betty, and Charles pull horizontally on an automobile tire at the angles shown in the picture.
The tire remains stationary in spite of the three pulls. Alex pulls with force F A of magnitude 205 N, and Charles pulls with force
F c of magnitude 184 N. Note that the direction of F c is not given. What is the magnitude of Betty's force F B if Charles pulls
in (a) the direction drawn in the picture or (b) the other possible direction for equilibrium?

(The director assures you it will all be very exciting.) The drawing below shows the situation. The SUV has four-wheel drive (see problem N5D.1), and the coefficients of friction between the tires and the pier’s surface are us =3/4 and uk = 1/2. Calculate the length L (as a fraction or multiple of D) of the run along the pier that you will need for the SUV to make it to the ferry. Ignore air drag.arrow_forward
