Atoy train has an acceleration of 1.2 m/s2. a net force of 3.0 n is acting on the train. what is the mass of the train?

2.5 kg

Explanation:

We can solve the problem by using Newton's second law:

where

F is the net force acting on the train

m is the mass of the train

a is the acceleration

For the toy train in the problem,

F = 3.0 N

a = 1.2 m/s^2

So we can solve the formula for m, to find the mass of the train:

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.
