A manager of a restaurant pushes horizontally with a force of magnitude 150 N on a box of melons. The box moves across the floor with a constant acceleration in the same direction as the applied force. Which statement is most accurate concerning the magnitude of the force of kinetic friction acting on the box?
friction is less than 150n
What statements are the choices? There are many possible true statements that could be made.
It is greater than 150 N
To determine the most accurate statement regarding the magnitude of the force of kinetic friction acting on the box, we can use Newton's second law of motion. The equation is Fnet = ma, where Fnet represents the net force acting on the object, m represents the mass of the object, and a represents the acceleration.
In this case, the manager is pushing horizontally with a force of 150 N. Since the box is moving with a constant acceleration in the same direction as the applied force, we can assume that there are no other significant forces acting on the box in the horizontal direction. Therefore, the net force (Fnet) is equal to the applied force (150 N).
To find the force of kinetic friction, we need to rearrange the equation to isolate the force of friction. The equation becomes Ffriction = Fnet - Fapplied.
Since the applied force (Fapplied) is 150 N and the net force (Fnet) is also 150 N in this case, the force of kinetic friction (Ffriction) would be zero. Therefore, the most accurate statement regarding the magnitude of the force of kinetic friction acting on the box is that it is zero.
