Question

An electric model train is accelerated at a rate of 8 m/s^2 by a 12 N force? What is the

mass of the train?

Answer 1

m = 1.5 kg

Step-by-step explanation:

Data:

• Aceleration (a) = 8 m/s²
• Force (F) = 12 N
• Mass (m) = ?

Use formula:

• 
  `\boxed{m = (F)/(a)}`

Replace in the formula:

• 
  `\boxed{m = (12N)/(8(m)/(s^(2)))}`

Equate the newtons:

• 
  `\boxed{m = (12kg*(m)/(s^(2)))/(8(m)/(s^(2)))}`

Simplify m/s²:

• 
  `\boxed{m = (12kg)/(8)}`

It divides:

• 
  `\boxed{m =1.5kg}`

What is the mass of the train?

The mass of the train is 1.5 kilograms.
