Hi everyone, I have a quick question about a HW question for Physics.

The question asks: If acceleration = force/mass (aka Newton's second law), what are the dimensions of force ?

So far, what I have is a=f/m, then f = a*m, so f = [L]/[T]^2 * m

However, no where in the book am I able to find the dimension of mass. Would it just be [M] ?

Thanks for your help!
