Question

What acceleration will a force of 20 newtons cause if applied to a go-kart with a mass of 20 kilograms

Answer 1

Force = Mass times Acceleration
\[F = MA\]

Rearranging to solve for Acceleration.
Acceleration = Force divided by Mass
\[A=\frac{ F }{ M }\]

Units must be the same
Grams, meters, seconds.

You can see you have Kilograms so a conversion is needed.

Answer 2

Just noticed Kg is actually the proper units.

Answer 3

if you are in S.I Units for Force. \[Newton = \frac{ Kg \times m }{ s^2 }\]
\[Mass = Kg\]
\[Acceleration = \frac{ m }{ s^2 }\]

So you do not need a conversion just the formula to solve for A, acceleration.
