# Lets drive to physics

If flat car is given an acceleration $$\text{a} = 3\text{ ms}^{-2}$$ starting from rest, compute tension (in $$N$$) in the light inextensible string connected to block $$A$$ of mass $$30\text{ kg}$$. Coefficient of friction between block and flat car is $$\mu = 0.50$$.

Neglect mass of pulley and its friction. Take $$g = 10\text{ ms}^{-2}$$.
