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 \(g = 10\text{ m/s}^2 \).
