The gravitational acceleration on Earth is 9.8 m/s². 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. 13,328 N

Answer :

The weight of the car on Earth is approximately 13,328 Newtons (N). Therefore, the answer is option d: 13,328 N.

The weight of an object on Earth can be calculated using the formula:

Weight (W) = Mass (m) × Acceleration due to gravity (g)

Where:

Mass (m) is given as 1360 kg.

Acceleration due to gravity (g) on Earth is approximately 9.8 m/s².

Now, plug in the values:

W = 1360 kg × 9.8 m/s²

W ≈ 13,328 N

So, the weight of the car on Earth is approximately 13,328 Newtons (N). Therefore, the answer is option d: 13,328 N.

The weight of a 1360 kg car on Earth is calculated using the formula w = mg, which gives a result of 13328 N. Therefore, option d is the correct answer.

The question asks for the weight of a car on Earth given that it has a mass of 1360 kg and the gravitational acceleration on Earth is 9.8 m/s2. To calculate the weight, use the formula w = mg, where w is the weight, m is the mass of the object, and g is the acceleration due to gravity. Plugging in the values given, we get:

w = (1360 kg)(9.8 m/s2)

w = 13328 N

Therefore, the weight of the car on Earth, to the nearest whole number, is 13328 N, which corresponds to option d.
