Question

You need to push a heavy box across a rough floor, and you want to minimize the average force applied to the box during the time the box is being pushed. Which method for pushing results in the minimum average force being applied to the box? Keep pushing the box forward at a steady speed, Push the box forward a short distance, rest, then repeat until finished, Push the box so that it accelerates forward at a constant rate. This would be the best method because the maximum coefficient of static friction is the coefficient of kinetic friction. o less than o greater than equal to So, the applied force required to the box's motion is relatively small. stop maintain increase start

Answer 1

Here ,

for the minimum average force applied force

keep pushing the box forward at a steady speed

-----------------------

the coefficient of the kinetic friction is larger than the kinetic friction

---------------------------------------

the applied force required to maintain the box's motion is relatively small
