A 52.5-kg sled is pulled across a horizontal icy surface as in the figure. The horizontal pulling force of magnitude P is directed opposite to a constant 35.0-N kinetic friction force. Starting from rest, the sled acquires a final speed of 2.25 m/s after being pulled a distance of 20.0 m. Two forces act on a sled that is on a horizontal surface. An arrow labeled vector fk extends from the left side of the sled and points left. An arrow labeled vector P extends from the right side of the sled and points right. The lengths of the arrows are approximately equal to each other. What is the magnitude P of the pulling force? N?

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
