a 90 kilogram dog runs across the dog park at a speed of 6.5 meters per second. what is the magnitude and direction of the average force required to stop the dog in .85 seconds?

am not sure about the answer

Explanation:

you need to find out the amount of force it's going in for example 10n or 100n then you need to times it the distance then devide by the time

be subject to a force andchange its motion

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
