Question 34

A rough plane is inclined at angle α \alpha\,α to the horizontal, where tan⁡α=512\displaystyle \tan\alpha=\frac5{12}tanα=125​. A block is released from rest on the plane. The coefficient of friction is 25\displaystyle \frac2552​. Take g=9.8g=9.8g=9.8 m s−2^{-2}−2.

a.

Find the acceleration of the block.

[6]
b.

Explain how the acceleration changes if the mass of the block is doubled.
