The gravitational acceleration on Earth is [tex]$9.8 \, m/s^2$[/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]$13,328 \, N$[/tex]

Answer :

To determine the weight of a car on Earth, we use the formula for weight:

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

Given:
- The gravitational acceleration on Earth is [tex]\( 9.8 \, \text{m/s}^2 \)[/tex]
- The mass of the car is [tex]\( 1360 \, \text{kg} \)[/tex]

Now, we just need to plug these values into the formula:

[tex]\[ \text{Weight} = 1360 \, \text{kg} \times 9.8 \, \text{m/s}^2 \][/tex]

Multiplying these values:

[tex]\[ \text{Weight} = 13328 \, \text{N} \][/tex]

Since the problem asks to round the weight to the nearest whole number, the final weight of the car is:

[tex]\[ 13328 \, \text{N} \][/tex]

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