How to find the magnitude of Force from an A vs Mass Graph

  1. Jun 15, 2017 #1
    1. The problem statement, all variables and given/known data
    I have attached the graph which displays Acceleration vs Mass. It shows the acceleration of objects of different mass that experience the same force. I need to get the magnitude of the force from this. ​

    2. Relevant equations

    F= ma
    3. The attempt at a solution
    I used F=ma for this but it was incorrect. If anyone can give me the right approach to this problem, it would be really helpful!

    It should be correct. Please show your working.

    Perhaps check your units?

    From the graph, I multiplied 600m*6m/s^2= 3600 Newtons. But the answer is coming out as wrong.

    It's not 600m you're multiplying (m means mass in that context) it's 600g.

    Yes sorry that was a typo, I meant 600 g. So shouldn't the answer be 3600 Newtons then? F=ma?

    No, the answer should then be 3600 g⋅m/s2

    You could also convert mass from grams to kilograms then multiply by acceleration in m/s2 to get a numerical answer in Newtons.
