Answer:
C
Explanation:
He was using visual clues to read the signs.
Check the current weather map for 2 different times, and see where the center of the storm is. That tells you what direction it's moving. With its speed and direction, you have its velocity.
Work = (force) x (distance)
80 J = (force) x (4 m)
Force = (80 J) / (4 m) = 20 N
That's IF the force was in the same direction as the 4m of motion.
If the force was kind of slanted, then it had to be stronger, and
it had a component of 20N in the direction of the motion.
If Adam is pulling with a pulling force of 120N, and the nets pulling force is 200N, and they are both going north, then that means that Krystal would have a a pulling force of 80N north, as 200N- 120N is 80N. She would be pulling north because she is on the same side as Adam, helping to pull the sled upwards.

C the milk carton has inertia
Inertia is an object not wanting to start moving when it's staying still, so the milk carton won't want to move and won't topple over
