2. Now, you are trying to move Spot on the ice (you are ice skating with him). You push
Spot with a force of 85 N, but a minor frictional force of 6 N opposes his motion.
a. What will Spot's acceleration be, assuming he has the same mass listed in
problem #1?
b. If you push Spot starting from rest, and he slides for 5.6 s, what will Spot's final
velocity be?
c. Let's say you now push Spot so that he has a velocity of 4.6 m/s. If he slides at this
rate for 3.2 s, how far will he slide?
