Problem 1 (25 pts) The figure shows a 2 kg box sliding down a 5-m-long inclined ramp in a packaging facility. The velocity of the box at the top of the ramp is 0.2 m/s. You want to know the velocity of the box at the bottom of the ramp. A. What is the system under study for this scenario? B. Write down the full conservation of energy equation that you'll use to determine the box velocity at the bottom of the ramp. Include all possible terms in your equation; that is, do not simplify the equation yet. Make sure you expand the system energy term to include all types of energy that could be important for this problem, e.g. internal energy. C. Assuming there is no friction between the box and the ramp, and that the change in internal energy is negligible, what is the box velocity at the bottom of the ramp? Be sure to start from the general conservation of energy equation you wrote down in part B, crossing out terms that you don't need for this analysis. D. Now assume there is a velocity-independent coefficient of sliding friction, p = 0.2, between the box and the ramp. Assuming both the change in internal energy and any heat generated by the friction are negligible, what is the box velocity at the bottom of the ramp? Again, be sure to start from the general conservation of energy equation you wrote down in part B, crossing out terms that you don't need for this analysis. Recall that the force on the box due to friction can be computed as Ffriction = un, where N is the normal force from the ramp on the box. L= 5 m 20
