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

Answer:

1.78

Step-by-step explanation:

$f = ma \\ a = \frac{f}{m} \\ a = \frac{8}{4.5}$

Answer 2

Answer:

The acceleration of train is 1.78  meter second²

Step-by-step 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 =  $\frac{8}{4.5}$ = 1.78 ms²

Hence The acceleration of train is 1.78  meter second²  Answer
