Question
A 6 kg block initially at rest is pulled to the right along a rough surface ( c) by a constant horizontal force of F = 12 N at an angle 0 = 30° as shown in the figure. The block is moved over a distance of 3 m and Its final speed is 2 m/s. F Find the following : 1. The normal force? 2. The work done by force F? 3. The total work done on the block? 4. The work done by frictional force? 5. The kinetic frictional force (f)? 6. The coefficient of kinetic friction (u,) between the block and the surface ? 7. The increase in the internal energy?
