An 50.0 N box is pulled 25.0 m up a 35.0° incline by an applied force of 100.0 N that points upward, parallel to the incline. If the coefficient of kinetic friction between the box and the incline is 0.220,
i. Draw the free body diagram of the said system
ii. Calculate the change in the kinetic energy of the box.
iii. Given initial speed of the box is 2.50 m/s, what is the final speed after it has moved 25.0 m up the incline.
