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!

We know the mass and the acceleration .

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

  (1)

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

Where;

And

We have to substitute the values in (1):

Finally:

the device is called “ rocket engine”

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
