Question

7. A box of mass 'm' is sent down an incline with an initial speed of 'v0' (down the incline). The incline makes an angle of '?' with the horizontal and the length of the incline is 'd'. The coefficient of kinetic friction between the box and the incline is '?k'. For the questions below- express your answers in terms of 'm', 'v0', '?', 'd', '?k' and 'g' (acceleration due to gravity). A. Draw a free-body diagram showing all the forces acting on the block as it slides down the incline. [4 Points] B. Find the Forces. [2 Points] (i) The component of box's weight acting down the slope. (ii) Force of friction C. Find Work [4 Points] (i) Work done by Friction as the box slides all the way down the incline. (ii) The work done by gravity over the same. D. Energy: [4 Points] What speed will it reach at the base of the incline?
