Question

If a car weighs 6310 N on earth, what is its mass?
a. 625kg

b. 663kg

c.682kg

d.644kg

Answer 1

Weight is a force and it can replace force in the equation. The acceleration would be gravity, which is an acceleration. Fw = 30 kg * 9.8 m/s^2 = 294 N. To change from weight to mass divide by gravity (9.8 m/s^2).
