Problem

Assertion: Two identical blocks are placed on a rough inclined plane. One block is given an initial velocity up the plane and the other down the plane. If

\mu=\frac13

and

\theta=45^\circ

, the ratio of the magnitudes of their accelerations is

2:1

. Reason: The desired ratio is

\frac{1+\mu}{1-\mu}
