A 25.0-kg box is released from rest on a rough in77 9tc)q.zcc8 vft,-faspn g lclined plane tyctp-dxk u(7w f4vh;2brpf 1d;c j -.yilted at an angle ot ;(fvy hfdjdk7crb xyp; w4pc-- .12uf $33.5^{\circ}$ to the horizontal. The coefficient of kinetic friction between the box and the inclined plane is 0.200.
(a) Draw the free-body diagram for the box.
(b) Determine the force of kinetic friction acting on the box.
(c) Determine the acceleration of the box as it slides down the inclined plane.
参考答案:
(a) The box is acted on by the force of gravity directed downward, the normal force due to the inclined plane directed perpendicular to the surface of the incline, and the force of friction due to the inclined plane directed parallel to the inclined surface in the direction opposite of the motion.
(b) 40.9 N
(c) $3.77 \; m/s^2$
