# A classical mechanics problem by Rishabh Deep Singh

A uniform block $$A$$ of length 6m and width 3m is hinged at $$C$$ and is supported by a small block shown in the figure above.

A constant force $$F = 400\text{ N}$$ is applied to the block $$B$$ horizontally.

What is the spped of $$B$$ after it move 1.5m?

Take the mass of block $$A$$ and $$B$$ to be 25 kg and 2.5 kg respectively. And take the coefficient of friction between all contact surface be 0.3.

With $$g = 10\text{ m/s}^2$$.
