Question

A toy 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?

Answer 1

2.5

Step-by-step explanation:

Answer 2

2.5 kg

Step-by-step explanation:

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

`F=ma`

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:

`m=(F)/(a)=(3.0 N)/(1.2 m/s^2)=2.5 kg`
