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

Sorry if i'm too late but i'm afraid Bubbletealuv's answer is incorrect.

If the cart had a mass of 8,000 kg and it was accelerating at a rate of 4 m/s2

Using the formula Force = mass * acceleration

The net force on the cart = 8000*4

= 32000 Newton  

Answer 2

F=m•a(squared)
F=8,000•4(squared)
F=8,000•16
F=128,000
then divide by 2 which is
64,000 Joules
