Question

The force on the last car of a train with a mass of 4.5 kg is 8.0 N. What is the train's acceleration in ms2?

Enter your answer as a decimal to the hundredths place, such as: 3.49

Answer 1

1.78

Explanation:

`f = ma \\ a = (f)/(m) \\ a = (8)/(4.5)`

Answer 2

The acceleration of train is 1.78 meter second²

Explanation:

Given as :

The mass of Train = 4.5 kg

The Force exerted on last car of train = 8 Newton

Let The acceleration of car = a ms²

∵ Force applied on body is the product of mass and acceleration of body

So , Force = Mass × Acceleration

Or, 8 Newton = 4.5 kg × a

∴ a =
`(8)/(4.5)` = 1.78 ms²

Hence The acceleration of train is 1.78 meter second² Answer
