If I have a trolley and an object on top traveling at constant speed, the force on the object in the horizontal direction must be zero.
In this case do we count there being no frictional force, or is it because the kinetic friction backwards and the static friction forwards sums up to zero? Is it right to say that there is this friction existent or is it not?
