Question

3. For each of the following, draw a free-body diagram and solve for the requested value. a. a block sits on an inclined plane without sliding. The box has a mass of 10 kg and the slope has a 30° angle with the horizontal. Solve for the magnitude of the friction. b. an elevator is being pulled upward at a constant velocity by a cable. The mass of the elevator is 100 kg. Solve for the tension. c. an elevator is being pulled upward at a constant acceleration by a cable. The mass of the elevator is 100 kg and the tension is 4000 N. Solve for the acceleration.
