Question:
A sled is pulled with a horizontal force of 20 N along a level trail, and the acceleration is found to be 0.40 m/s2. An extra mass m = 4.5 kg is placed on the sled. If the same force is just barely able to keep the sled moving, what is the coefficient of kinetic friction between the sled and the trail?
Step by Step Answer:
Use Newtons second law and the expression for kinetic friction Se...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
