WebSep 13, 2024 · First, as you have found, the static friction force is in fact acting down the ramp. This is because at 10 c m down the incline, the spring force is larger than the gravitational force. Therefore, the block would "want" to move up the incline, but if static friction is causing the block to be at rest, then it must be acting down the incline. WebThe work done against friction is:-. (take g=10m/s 2) Medium. View solution. >. A body is moving up on an inclined plane of angle θ with an initial kinetic energy E, the coefficient of friction between the plane and the body is μ. The work done against friction before the body comes to rest is: Medium. View solution.

WebSep 18, 2024 · The kinetic friction between the object and the ramp is $\mu_k=0.06$. How long does it take for the object to reach the bottom? Solution: The only force exerting on the object and forcing it to go down is the component of weight parallel to the inclined plane. The kinetic friction force, up the incline, opposes the weight force down the incline. WebOct 19, 2024 · Friction is a force that opposes the motion, so it acts in the direction opposite the motion. These forces are illustrated in the free-body diagram. Diagram showing the frictional force on an ...
