True / False:
If a 40 kg person is accelerating at 10 m/s^2,then the magnitude of the force acting on him or her is 400 N.
1.How much force is needed to make a 60 kg object accelerate at a rate or 2.0 m/s ^2?
2.What is the acceleration of a 30 kg objedct when 180 n of force is aplied to it?
3.Which of the following equation shows how you would solve for mass if you know the force acting on an object and the accleration of an object?
a~m=f/a
b~m=fa
C~m=a/f
d~m=f-a

thax emma your the best
You can apply Newton's Second Law, which is essentially Force = Mass x Acceleration.
For the first question, have a mass of 40kg and an acceleration of 10m/s^2, which means that the Force will be 400N.
1. Calculate force by multiplying mass by acceleration, so 60kg x 2.0m/s^2 which will result in a force of 120N.
2. You can rearrange the variables in the equation F=m*a as a=F/m. Take the force applied and divide it by the mass, so 180N / 30kg which is 6m/s^2.
3. If you know the force and acceleration of the object, you can rearrange the equation F=ma to m=F/a.

Thank you so much that helped me so much
omg i got a 100% tanks sooo much!!!!!
Thank u
thanks emma!
If you just want the answer, then look at the 10 answer sheets posted already. However if you want to know why then here:
If a 100 kg person traveled at 5m/s^2 or meters per second squared there would be 500 newtons acting on that person, because F=M*A or Force equals mass times acceleration. Acceleration would be the speed, so the 5m/s^2 and mass would be 100 kg. This makes the equation F=100*5, making the answer 500=100*5.
Thanks Emma
Good for Oct 2020
Thank You Emma
Thanks your awesome Emma
yes [true, c, a, a.]
Love how this conversation has gone from the beginning of 2015 to 2021. A whopping 6 years ago. If any 2015 people want to come back to the conversation that would be awesome.

is no one gonna question how emma just replied to herself and said to listen to her on her own account
@banana same here. six years of being confused and finding help lol
thx emma
answers are correct for 2021 oh and Thanks Emma 100%!
thanks lgbtq+ person I got 100%
I think "Human" is talking about a different test btw.
OMG THANK YOU SO MUCH EMMA I GOT 100 IM NOT JPKING WTF YOUR A LIFE SAVER
The student named “Emma” is correct! Also congratulations 🎉🎊🎈🍾 on getting more then 100 likes on your answer!! ✅ ✅ ✅

I just took the quick check and got 100. Don't listen to anyone else that tells you these arent the answers. THEY ARE THE ANSWERS AS OF APRIL 2020
wait up that is my name spelled exactly. makayla yeah.
Emma, mind your own business.
Guys, it's Tristan is right.
Also, remember for the future...it's just Force = to mass times acceleration. You can do it. xoxo
Btw, you guys should learn how to answer this stuff on your own. The next question I'm answering I'll say the answer wrong. Start studying, it will pay off, trust me
