In this question, use g=9.8 m s−2g = 9.8 \text{ m s}^{-2}g=9.8 m s−2.
A small block, PPP, is pulled across a rough horizontal plane.
A horizontal pulling force of magnitude TTT newtons acts on PPP.
PPP moves with a constant acceleration of 1.2 m s−21.2 \text{ m s}^{-2}1.2 m s−2.
PPP has a weight of 1.47 N1.47 \text{ N}1.47 N.
The only resistance force acting on PPP is due to friction.
The coefficient of friction between PPP and the plane is 0.350.350.35.
Find TTT.
