Question 83

In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.

Two blocks PPP, of mass 5 kg, and QQQ, of mass 3 kg, rest in contact with each other on a rough horizontal floor.

A horizontal force of magnitude 40 N is applied to PPP, pushing both blocks along the floor. The coefficient of friction between each block and the floor is 0.2.

a.

Find the acceleration of the blocks.

[3]
b.

Find the magnitude of the force exerted by P P\,P on QQQ.
