Question 4

Use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.

A robotic transport sled S S\,S is pulled across a rough horizontal factory floor by a horizontal pulling force of magnitude P P\,P newtons.

S S\,S has weight 15.68 N and moves with constant acceleration 1.25 m s−2^{-2}−2. The only resistance to motion is friction, and the coefficient of friction between S S\,S and the floor is 0.3.

Find the value of PPP.
