# A classical mechanics problem by jatin yadav

Consider the arrangement consisting of a wedge (radius $$R = 2$$ meters) and a small block , both having same mass, $$m$$. The wedge is free to move.The upper surface of wedge is semicircular. Initially, both of them are rest. The block is released from A as shown in the figure. The speed of the wedge(in $$m/s$$) can be expressed as $$f(\theta)$$. Find $$100 f'(\theta)$$ at $$\theta = \frac{\pi}{4}$$ to the nearest integer

_Details and Assumptions _

• All surfaces are perfectly smooth.

• The block never topples.

• $$g = 9.8 m/s^2$$
