Concept explainers

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

What distance does the box move from its position at t=0 before its speed is reduced to zero?

If the force continues to be applied, what is the velocity of the box at 3.00 s ?

The frictional force acting on the sled is one‑fifth of the combined weight of the child and the sled. If she travels for a distance of 26.5 m and her speed at the bottom is 3.70 m/s, calculate the angle θ that the slope makes with the horizontal.
