A cardboard carton weighing 165 newtons is resting on a marble floor. If the coefficient of friction between cardboard and smooth marble is 0.20, how much force would it take to keep the box sliding along at a constant speed?
165 * .2 = 33 N
To determine the force required to keep the cardboard carton sliding along at a constant speed, we need to consider the force of friction acting on the box.
The force of friction can be calculated using the formula:
Friction force = coefficient of friction × normal force
The normal force in this case is the weight of the carton, which is equal to 165 newtons.
Let's calculate the friction force:
Friction force = 0.20 × 165
Friction force = 33 newtons
Therefore, it would take an additional force of 33 newtons to keep the box sliding along at a constant speed.
