You are pushing a 20-kg box along a horizontal floor. friction acts on the box. when you apply a horizontal force of magnitude 48 n, the box moves at a constant velocity. if you increase your horizontal pushing force to 100 n, what is the acceleration of the box?

=force × distance a. work b. velocity c. pressure d. momentum
