Figure Ex5.7 shows the velocity graph of a 5.0 kg box as it pushed to the right (->) along a horizontal surface. Assume that a 12 newton friction force acts on the box to the left (<-) during its the entire motion.
What is the amount of right-ward (->) acting push on this object at the given times?
t=2 N=?
t=7 N=?
