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

a = acceleration of the bank cart = 4 m/s²

m = mass of the bank cart = 8000 kg

F = net force on the cart

According to newton's second law , Net force is the product of mass of the object and the acceleration of the object.

Net force = mass x net acceleration

hence Net force acting on the cart is given as

F = ma

F = 8000 x 4

F = 32000 N

hence the net force acting on the cart comes out to be 32000 N
