    Slanted surfaces with friction: A box is sliding down an incline tilted at a 12.0° angle above horizontal. The box is initially sliding down the incline at a speed of 1.50 m/s. The coefficient of kinetic friction between the box and the incline is 0.340. How far does the box slide down the incline before coming to rest? a) Draw Free Body diagrams for the two masses b) Write the equations for the two masses in the direction of motion...
