Finding mass using acceleration and force

[From: ] [author: ] [Date: 11-05-10] [Hit: ]
What is the mass of an object that accelerates to 5 m/s^2 with a force of 30 N?I know you can find acceleration by dividing force by mass and you can find force by multiplying acceleration and mass, but I have no idea of how to find mass by utilizing those two units. Im not asking for the answer, just the equation.m = F/a which makes it easy to substitute to get the answer.......
Okay, so I'm in 8th grade physics.
The question is, "What is the mass of an object that accelerates to 5 m/s^2 with a force of 30 N?"
I know you can find acceleration by dividing force by mass and you can find force by multiplying acceleration and mass, but I have no idea of how to find mass by utilizing those two units. I'm not asking for the answer, just the equation.

Start with F= ma ( force = mass * acceleration)

divide both sides by a and you get

m = F/a which makes it easy to substitute to get the answer.
