Benjamin Barton · Answer 1

- - "Constant velocity" means the acceleration of the object is zero.

- - "Zero acceleration" means that all the forces on the object add up to zero.

- - If a force of 50-newtons is pulling the object in one direction

and the object's speed is constant, then the frictional force on

the object must be 50 newtons in the opposite direction.
