A 10.0kg box accelerates across the floor at 1.5m/s^2 when pulled by a force of 20N acting horizontally, The same box is then pulled by the same force acting at an elevation of 40 degrees.

A. Draw the free-body diagrams for both situations.

B. Determine the coefficient of sliding friction.

C. Calculate the acceleration of the box if the force is directed at 40 degrees above the horizontal. Draw the free-body diagram for this situation.

A 200kg box is being pulled up an incline that is angled 24 degrees to the horizontal. The applied force used to get the box to travel up the incline is in a direction parallel to the incline. The coefficients of friction between the incline and the box are μs= 0.65 and μk= 0.40. Once the box starts moving up the incline, it accelerates at a constant 1.50 m/s^2. a) Draw the free-body diagram that shows this situation b) What...
