1. A box is sliding up an incline that makes an angle of 20 degrees with respect to the horizontal. The coefficient of kinetic friction between the box and the surface of the incline is 0.2. The initial speed of the box at the bottom of the incline is 2 m/s. How far does the box travel along the incline before coming to rest?
2. A 10.0 kg box is attached to a 7.00 kg box which rests on a 30 degree incline. The coefficient of kinetic friction between each box and the surface is 0.10. Find
a) the rate of acceleration of the system.
b) the tension in the rope
