Consider the following situation. A block of mass 20 kg is initially at rest on an inclined that makes an angle of 37 degrees with the horizontal. The block is now being pulled up the plane by a rope with a tension of 250 N and also the rope makes an angle of 37 degrees to the plane (to the plane, not to the horizontal). If the frictional force experienced by the block, is 8 N, the acceleration of the block is > ? < m/s2. Calculate your answer to one decimal point.
