(II) The carton shown in Fig. 4−55 lies on a plane tilted at an angle θ = 22.0° to the horizontal, with μk = 0.12. (a) Determine the acceleration of the carton as it slides down the plane. (b)(b) If the carton starts from rest 9.30 mm up the plane from its base, what will be the carton's speed when it reaches the bottom of the incline?
