Question

How fast will an object with a mass of `8 kg` accelerate if a force of `32 N` is constantly applied to it?

Answer 1

`4"ms"^{-2}`

Explanation:

We must assume that there are no other external forces acting on the object in question. In that case, the net force (which is the sum of all the forces acting on the object) is just `32"N"`.

Newton's Second Law states that

`F_"Net" = ma`,

where

`F_"Net"` refers to the net force acting on the object,

`m` refers to the mass of the object,

`a` refers to the acceleration of the object.

When we substitute our values into the equation, we get

`32"N"=(8"kg")a`.

Therefore,

`a=4"ms"^{-2}`
