The carton shown lies on a plane tilted at 22.0° to the horizontal, with a µk of 0.12.
(a) Draw a free body diagram and calculate the acceleration of the carton as it slides down the incline. Use the summation of the forces in the x-direction and the y-direction to find your answer.
(b) If the carton starts from rest 9.30m from the base of the incline, what will be the carton's speed as it reaches the bottom of the incline?
