Question

If a car weighs 6310 N on earth, what is its mass?

Answer 1

Answer:

If a car weighs 6310 N on earth, its mass = 643.22 kg.

Explanation:

Weight of a body is given by the product of it's mass and acceleration due to gravity on that planet.

 So weight of body in earth = mass of body* acceleration due to gravity on earth.

 Acceleration due to gravity in earth = $9.8m/s^2$

 Here it is given weight of car = 6310 N

  So we have,  6310 = mass of car* 9.81

                           Mass of car = 6310/9.81 = 643.22 kg.

 So If a car weighs 6310 N on earth, its mass = 643.22 kg.
