A block of mass M is being pulled by a rope under tension that is angled 0 degrees
above the horizontal. The block slides horizontally along a rough horizontal
surface.
= tension in the rope
n = normal force acting on the block by the surface
f = frictional force between the block and the surface
a = non-zero acceleration of the block

Expert Solution

Step 1
Objects on an inclined plane are nevertheless subject to this concept. The force of gravity is divided as the plane's angle increases. Because the object is sliding horizontally, the normal force must still resist the downward portion of gravity, but it will be less than the total gravitational force.
The normal force diminishes as the angle increases, thus the friction force must decrease as well. When the normal force is zero, the friction force is also zero.
