Question 102

A block of mass 5 kg rests on a rough horizontal floor. The coefficient of friction is 0.3. A horizontal force of magnitude P P\,P N is applied. Take g=9.8g=9.8g=9.8 m s−2^{-2}−2.

a.

Find the greatest value of P P\,P for which the block remains at rest.

[3]
b.

Find the actual friction force when P=10P=10P=10 N.
