Elena dimabato of Anolia, the princess who always cried, has an ugly block with a mass M = 8 kg that slides to the right across a rough horizontal surface with a speed of 4 m/s. There is a light rope which tugs on the block with a force T= 8 N. This is oriented above the horizon which is α = 28°. Moreover, the coefficient of kinetic friction between the surface and the ugly block is 0.312. what is the strength of tension needed for the block to stop moving at 1 meter from its initial position?

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
