Question

A 24-N net force acts on a 8-kg rock.What is the acceleration of the rock?

Answer 1

You need to re-arrange the formula F = ma which is Force = mass * acceleration.

If F = ma, then to find a you need to divide F by m. So a = F / m or acceleration = Force / mass.

You then just input your values, so 24 / 8.

24 / 8 = 3.

Hopefully this helps (and it's right aha).

Answer 2

`3 m/s^2` is the acceleration of the rock.

Step-by-step explanation:

Force is defined product of mass of an object and acceleration by whihc object is moving.

Force(F) =
`mass(m)* acceleration (a)`

Given mass of a rock = 8 kg

Acceleration of the rock = a = ?

Net force on the rock = F = 24 N

Putting in the values we get,

`F=m* a`

`a=(F)/(m)=(24 N)/(8 kg)=3 m/s^2`

`3 m/s^2` is the acceleration of the rock.
