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

Answer:

m = 1.5 kg

Explanation:

Data:

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

Use formula:

• $\boxed{m = \frac{F}{a}}$

Replace in the formula:

• $\boxed{m = \frac{12N}{8\frac{m}{s^{2}}}}$

Equate the newtons:

• $\boxed{m = \frac{12kg*\frac{m}{s^{2}}}{8\frac{m}{s^{2}}}}$

Simplify m/s²:

• $\boxed{m = \frac{12kg}{8}}$

It divides:

• $\boxed{m =1.5kg}$

What is the mass of the train?

The mass of the train is 1.5 kilograms.
