Two blocks are connected by a massless rope over a frictionless pulley, as shown in the diagram below. There is a coefficient of kinetic friction of uk = 0.3 between the inclined plane and block A. Let Mass B = 0.2 kg, and Mass A = 2 kg, and let the angle of the incline be e = 30°. Assuming that the mass A is moving downward: a) By writing down the relevant Newton's Second law equations for each block, and for each relevant axis, calculate the acceleration of the system. Is this acceleration sufficient to make the block B move downward? b) The tension in the rope

Free Body Diagram

The system of forces acting on a body tends to either rotate it or make the body undergo motion. In general, when an external agent exerts a force on a body, the body undergoes translational motion and rotational motion. The body has six degrees of freedom under the influence of that force. Here, three degrees of freedom are from the translational motion while the other three are from the rotation motion. However, sometimes the bodies are not allowed to undergo any motion and are fixed, under such conditions the body is said to be constrained.
