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

## Homework Statement

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.​

F= ma

## 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![/B]

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.

600m*6m/s^2= 3600 Newtons
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.
