A bedroom bureau with a mass of 45 kg, including drawers and clothing, rests on the floor.
Question:
A bedroom bureau with a mass of 45 kg, including drawers and clothing, rests on the floor.
(a) If the coefficient of static friction between the bureau and the floor is 0.45, what is the magnitude of the minimum horizontal force that a person must apply to start the bureau moving?
(b) If the drawers and clothing, with 17 kg mass, are removed before the bureau is pushed, what is the new minimum magnitude?
Step by Step Answer:
We do not consider the possibility that the bureau might tip and treat this as a purely ho...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.
