The gravitational acceleration on Earth is [tex]$9.8 \, \text{m/s}^2$[/tex]. What is the weight of a car on Earth (to the nearest whole number) if it has a mass of 1360 kg?

A. 14 N
B. 139 N
C. 1333 N
D. [tex]$13,328 \, \text{N}$[/tex]

Answer :

To find the weight of the car on Earth, we can use the formula:

[tex]\[ \text{Weight} = \text{Mass} \times \text{Gravitational Acceleration} \][/tex]

Here’s how you can calculate it step-by-step:

1. Identify the mass of the car: The mass is given as 1360 kg.

2. Identify the gravitational acceleration on Earth: This is given as [tex]\(9.8 \, \text{m/s}^2\)[/tex].

3. Substitute the values into the formula:
[tex]\[
\text{Weight} = 1360 \, \text{kg} \times 9.8 \, \text{m/s}^2
\][/tex]

4. Calculate the weight:
[tex]\[
\text{Weight} = 13328 \, \text{N}
\][/tex]

5. Round to the nearest whole number (if needed): In this case, the calculated weight is already a whole number: [tex]\(13,328 \, \text{N}\)[/tex].

Therefore, the weight of the car on Earth is approximately 13,328 N.
