A uniform block A of mass 25 kg and length 6m is hinged at C and is supported by a small block B as shown in the figure .a constant force F of magnitude 400 N is applied to block B horizontally.what is the speed of B after it moves 1.5m ? The mass of block B is 2.5 kg and the co-efficient of friction for all the contact surfaces is 0.3

**Details and Assumptions**

- Use \(\ln\frac{3}{2} =0.41\)
- \(g=10\) ms\(^{-2}\)
