A 600 N block rests on a 30° plane. If the coefficient of friction is 0.20, what is the value of the force, P, applied horizontally to keep the block moving up the plane?
Added by Nieves W.
Step 1
The forces acting on the block are the gravitational force (weight), the normal force, the frictional force, and the applied force, P. The gravitational force can be split into two components: one perpendicular to the plane (which affects the normal force) and one Show more…

A 60 kg block rests on a rough plane inclined at 30 deg with the horizontal. The coefficient of sliding friction between block and plane is 0.15. What force P parallel to the plane is required to keep the block moving up the plane at constant speed?

ao A $2.5 \mathrm{~kg}$ block is initially at rest on a horizontal surface. A horizontal force $\vec{F}$ of magnitude $6.0 \mathrm{~N}$ and a vertical force $\vec{P}$ are then applied to the block (Fig. $6-17$ ). The coefficients of friction for the block and surface are $\mu_{s}=0.40$ and $\mu_{k}=0.25 .$ Determine the magnitude of the frictional force acting on the block if the magnitude of $\vec{P}$ is (a) $8.0 \mathrm{~N}$,(b) $10 \mathrm{~N}$, and $(\mathrm{c}) 12 \mathrm{~N}$
