Question

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

Answer 1

0.3 m/s2

Explanation:

You use the equation `F=ma` to solve this.

F = 2 N
m = 7 kg
a = ?

If you rearrange the formula above to solve for "a", you get
`a=F/m`
`a=(2 N)/(7kg)`
`a=0.2857 m/s^2`

Round to the correct number of significant figures (1) and you get:
`a=0.3 m/s^2`
