Remember Isacc Newton's second law--- Force= mass* acceleration

anonymous · Answer

I don't get nothing from physics my teachers makes it to hard to understand

anonymous · Answer

basically figure out this---1.35=m*1.5

anonymous · Answer

it says "A force of 1.35 newtons" so that your force and says "accelerate a book by 1.5 meters/seconds^2" so that is your acceleration and you need to find the mass so use the formula above :)

anonymous · Answer

alright

anonymous · Answer

you can also think 1.35=m*1.5 as--- 1.35 divided by1.5 :)

anonymous · Answer

Does that make sense?

anonymous · Answer

so I just divided 1.35 by 1.5

anonymous · Answer

yes and it will give you the mass of the book :D

thanks :)
