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?

STALIN [3.7K]

Answer:

2.5 kg

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:

$m=\frac{F}{a}=\frac{3.0 N}{1.2 m/s^2}=2.5 kg$
