Thank you so much you are very smart

Why were you not reporting the decimals on the first 2 problems?

think you was great help

very helpful! thank you so much!

Very nice video.Thanks.

Sloane, We didn't know the mass of the semi until the end of the problem. We had to divide the gravitational force by ten to get the mass, and then we converted it from kg to lbs. The 80,000 lbs, is the max weight, but not the actual weight of the semi.

Hey this is Sloane, On number 8, why didn't we multiply the mass of the semi truck by 10? wouldn't that be the gravitational force?
