# How fast will an object with a mass of 7 kg accelerate if a force of 2 N is constantly applied to it?

Jan 5, 2016

0.3 m/s2

#### Explanation:

You use the equation $F = m a$ to solve this.

F = 2 N
m = 7 kg
a = ?

If you rearrange the formula above to solve for "a", you get
$a = \frac{F}{m}$
$a = \frac{2 N}{7 k g}$
$a = 0.2857 \frac{m}{s} ^ 2$

Round to the correct number of significant figures (1) and you get:
$a = 0.3 \frac{m}{s} ^ 2$
