When a mover pushes with a constant sideways force of 20 N on a 15 kg box, the box moves along the floor at a constant speeed of 2m/s, What is the net force on the box?
To find the net force on the box, we need to understand the concept of net force and how it relates to the given information.
Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration or deceleration. In this case, the box is moving at a constant speed, which means there is no acceleration. Therefore, the net force on the box must be zero.
Since the mover is pushing the box with a constant sideways force of 20 N, and the box is moving at a constant speed of 2 m/s, we can conclude that the net force acting on the box is zero.
This is because the frictional force acting in the opposite direction of the applied force must be equal in magnitude to the applied force, thus cancelling out each other and resulting in zero net force.
Therefore, the net force on the box is 0 N.
