7. A 30 kg box is placed on a 29-degree incline. The ramp is frictionless. The box is released from the top and slides 5 meters down the ramp. Create a free-body diagram for the box on the ramp. Label the forces in the direction of motion (up and down the ramp) and the forces in the non-motion direction (in and out of the ramp). (b) Write an equation for the forces in the non-motion direction. Solve for FN. (c) Write an equation for the forces in the direction of motion. Solve for the acceleration of the box. (d) How much time does it take for the box to slide 5 meters down the ramp?
