Question

A block of mass 2.30kg is accelerated across a rough surface by a rope passing over a pulley.

a) The tension in the rope is 12.4N, and the pulley is 11.2cm above the top of the block. The coefficient of kinetic friction is 0.415. Determine the acceleration of the block when x = 0.450m.

b) Calculate the value of x at which the acceleration becomes zero.
