A box is pulled 6 meters across the ground at a constant velocity by a horizontally applied force of 50 newtons. At the same time, kinetic friction acts on the box as it slides so that it eventually stops when the pulling force stops. What is the magnitude of the frictional force

The magnitude of the frictional force is 50 newtons.

Explanation:

The frictional force can be found as follows:

Where:

F: is the applied force = 50 N

: is the frictional force

m: is the box's mass

a: is the acceleration

Since the box is pulled at a constant velocity, a = 0, so:

Therefore, the magnitude of the frictional force is equal to the applied force, that is to say, 50 newtons.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
