A clever coyote uses rocket powered skates to try to catch a roadrunner. The mass of the coyote is 38.1 kg.If the coyote starts from rest, and accelerates to a final speed of 26 m/s in a distance of 2.4 m. How fast is the coyote moving when he has traveled 2.11m while he is slowing down? Assume his initial speed when he is slowing down is equal to his final speed when the rockets were firing.

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.
