Question

Harry and Hagrid needed to get money out of Gringotts bank. The bank cart was accelerating at a rate of 4 m/s2 and it had a mass of 8,000 kg. What is the net force acting on the cart?

USE THE FORMULA: F=m∙a Show all your work!

Answer 1

We know the mass
`m` and the acceleration
`a`.

If we want to know the net force
`F` and assuming there is not Force of Friction, we have to use the following equation:

`F=ma` (1)

This formula is the result of Newton’s Second Law of Motion:

Where;

`m=8000kg`

And

`a=4(m)/(s^(2))`

We have to substitute the values in (1):

`F=8000kg(4(m)/(s^(2)))`

Finally:

`F=32000N`
