[问答题]
A 25.0-kg box is relca fp0* :2cgbs8wam,jeased from resw -s+-n6 3 ogia3z sy2z1(iw8 chfporst on a rough inclined plane tilted at an angle ( yog2 pwfzc8w-ro zs-36 i1a3n+s ihsof $33.5^{\circ}$ 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) $3.77 \; m/s^2$
