If the coefficient of friction is Of and the inclination angle is 30°, find the acceleration of the system and the tension in the cord joining two masses Datum m₂3. Consider an inclined plane with two balls suspended as shown below. The pulley has negligible mass and both the pulley and the surface of the incline are frictionless.a. If one of your classmates calculated that, once released, the acceleration of the blocks would be 43?, without doing any calculations, say whether or not this could be a reasonable value for the acceleration.b. Draw and label a free body diagram (FBD) for each ball. (Don’t break any forces into components for the FBDs—save that work for the next question. Be sure your drawings show clearly any information you know about the directions and relative magnitudes of the forces.) Rank the relative magnitudes of all forces in your FBDs.
