A trunk with a weight of 220 N rests on the floor. The coefficient of static friction
Question:
(a) What is the magnitude of the minimum horizontal force with which a person must push on the trunk to start it moving?
(b) Once the trunk is moving, what magnitude of horizontal force must the person apply to keep it moving with constant velocity?
(c) If the person continued to push with the force used to start the motion, what would be the magnitude of the trunk's acceleration?

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.
