Question 81

A crate of mass 10 kg rests on a rough horizontal floor. The coefficient of friction is 0.4. A horizontal force of 15 N is applied to the crate, but the crate remains at rest. Take g=9.8g=9.8g=9.8 m s−2^{-2}−2.

a.

Find the greatest possible friction force.

[2]
b.

Find the actual friction force.

[1]
c.

Explain why the actual friction force is not equal to μR\mu RμR.
