Hard

Solving time: 4 mins

pulling it at $3 0^{\circ}$ with horizontal and $B$ is pushing it at $3 0^{\circ}$ with horizontal. $(g = 10 m s^{- 2})$ Two identical rollers, each of mass $100 kg$ , are on a rough horizontal ground. Two persons $A$ and $B$ are moving these (a) What is the net force acting on the rollers used by A rollers on the ground with same horizontal acceleration of and $B$ ? (b) Out of $A$ and $B$ , who is exerting the minimum force $1 m s^{- 2}$ , along the ground. The coefficient of friction between the roller and ground is $μ_{s} = 0.25$ and $μ_{k} = 0.20$ . A is and maximum force on the roller? Explain.
