Question 5

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

A small block P P\,P is pulled across a rough horizontal plane by a horizontal pulling force of magnitude T T\,T newtons.

P P\,P has weight 1.47 N and moves with constant acceleration 1.2 m s−2^{-2}−2. The only resistance to motion is friction, and the coefficient of friction between P P\,P and the plane is 0.35.

Find the value of TTT.
