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 a car on Earth, we use the formula for weight, which is:

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

Here's a step-by-step solution:

1. Identify the Mass and Gravitational Acceleration:
- The mass of the car is given as [tex]\( 1360 \, \text{kg} \)[/tex].
- The gravitational acceleration on Earth is [tex]\( 9.8 \, \text{m/s}^2 \)[/tex].

2. Plug in the Values:
- Substitute the mass and gravitational acceleration into the formula:
[tex]\[ \text{Weight} = 1360 \, \text{kg} \times 9.8 \, \text{m/s}^2 \][/tex]

3. Calculate the Weight:
- Multiply the mass by the gravitational acceleration:
[tex]\[ \text{Weight} = 13328 \, \text{N} \][/tex]

4. Round the Result:
- Since we need the weight to the nearest whole number, the calculated result is already a whole number.

So, the weight of the car on Earth is [tex]\( 13,328 \, \text{N} \)[/tex].
