Question

A wooden block of mass m resting on a rough horizontal table is pulled by a force F as shown in the figure. If μ is the coefficient of friction between block and table, its acceleration will be, μ F ⁡ cos θ m ⁡, μ F ⁡ sin θ m ⁡, F ⁡ m ⁡ cos θ + μ sin θ - μ g ⁡, F ⁡ m ⁡ cos θ - μ sin θ

Forces acting on the mass are shown in figure. For vertical direction no motion occurs ∴ R ⁡ + F ⁡ sin θ = mg Along horizontal F ⁡ cos θ - f ⁡ = ma , where a is acceleration or F ⁡ cos θ - μ R = ma F ⁡ cos θ - μ mg - F ⁡ sin θ = ma a ⁡ = F ⁡ m ⁡ cos θ + μ sin θ - μ g
