Neco 2021 Physics Question 4
Practice essay / theory question 4 from the 2021 Neco Physics examination. This question covers forces, friction, Newton's laws, vectors .
A 5.0 kg block rests on a rough horizontal floor. A force of magnitude 40 N is applied to the block at an angle of 30° above the horizontal, directed to the right. The block is also attached to a light rope that pulls horizontally to the left; the tension in the rope is T (unknown). The coefficient of static friction between the block and the floor is 0.40 and the coefficient of kinetic friction is 0.30. The force diagram shown in the illustration represents all the forces acting on the block: its weight (W) acting vertically downwards, the normal reaction (R) acting vertically upwards, the applied force (F) of 40 N at 30°, the tension (T) acting horizontally to the left, and the frictional force (f) opposing the motion. Using the information given and the diagram, answer the following questions.
