Question 42

Use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.

A block of mass 2 kg is at rest on a rough plane inclined at an angle θ \theta\,θ to the horizontal, where tan⁡θ=0.75\tan\theta = 0.75tanθ=0.75. The coefficient of friction between the block and the plane is 0.2.

The block is released from rest.

Find the acceleration of the block.
