# Graphing Velocity of a Box When a Force Acts on It

APPH12-E0RJWD

You are pulling a box on a horizontal surface with an applied force exactly equal to the force of kinetic friction for $5\text{ s}$. The applied force acts parallel to the surface. You then you double the applied force for another $5\text{ s}$.

Which of the following graphs is representative of the velocity of the box during this $10\text{ s}$ interval?

A
B
C
D
