The diagram below shows a block (A) with mass 5 kg resting on a rough surface. Block B, with unknown mass, is placed on top of block A. Attached to block A is a light, inextensible string, running over a frictionless pulley and holding mass piece C of 3 kg. The rough surface has coefficient of static friction of 0,2. The tension in the rope is T 3.1 3.2 3.3 3.4 3.5 B A 5 kg T C 3 kg Define the term frictional force in words. Determine the value of T. What is the magnitude of the frictional force required for block A to be at rest. Calculate the minimum mass of block B to prevent block A, from moving. Block B is now removed and the system starts accelerating at 3 m.s-. 3.5.1 Draw a free-body diagram of block C while it accelerates. 3.5.2 Calculate the tension in the string joining block B and C. 3.5.3 Determine the frictional force acting on block A while accelerating.
