Question

How fast will an object with a mass of `4 kg` accelerate if a force of `23 N` is constantly applied to it?

Answer 1

`6m/s^2`

Explanation:

Using Newton's `2^"nd"` Law, we can determine the acceleration of the object.

Recall his formula:

`color(blue)(|bar(ul(color(white)(a/a)F_"net"=macolor(white)(a/a)|)))`

where:
`F_"net"=`force (Newtons)
`m=`mass (kilograms)
`a=`acceleration (metres per second)

Rearrange the formula for `a` and substitute your known values into the formula to solve for the acceleration of the object.

`F_"net"=ma`

`a=F_"net"/m`

`a=(23N)/(4kg)`

`a=5.75`

`a~~color(green)(|bar(ul(color(white)(a/a)6m/s^2color(white)(a/a)|)))`
