ANSWER
[tex]a = f \div m [/tex]
EXPLANATION
The force of an object (f) is equal to its mass (m) times its acceleration (a). Thus, the formula for calculating force is f = ma.
We want to solve this relation for 'a'.
We need to divide both sides by 'm'
This implies that,
[tex] \frac{f}{m} = \frac{ma}{m} [/tex]
We cancel out the common factors on the right hand side to obtain:
[tex] \frac{f}{m} = a[/tex]
We can rewrite this as:
[tex]f \div m = a[/tex]
Or
[tex]a = f \div m [/tex]
The correct choice is B.
