Question

A 16.3 kg block is dragged over a rough, horizontal surface by a constant force of 184 N acting at an angle of angle 34.9 ? above the horizontal. The block is displaced 44 m and the coefficient of kinetic friction is 0.131. 16.3 kg µ = 0.131 184 N 34.9 ? Find the work done by the 184 N force. The acceleration of gravity is 9.8 m/s 2 . Answer in units of J. 005 (part 2 of 5) 10.0 points Find the magnitude of the work done by the force of friction. Answer in units of J. 006 (part 3 of 5) 10.0 points What is the sign of the work done by the frictional force? 1. negative 2. zero 3. positive 007 (part 4 of 5) 10.0 points Find the work done by the normal force. Answer in units of J. 008 (part 5 of 5) 10.0 points What is the net work done on the block? Answer in units of J.
