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 = = 1.78 ms²
Hence The acceleration of train is 1.78 meter second² Answer
