[问答题]
A 25.0-kg box is rels7seof nl6no,q*,c-m nh )rx /w9gb3qeased from rest on a rough inclined plane tilted at an angle hbg 3xr)qn9/w of $33.5^{\circ}$ 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) $3.77 \; m/s^2$
