A certain car of a certain mass will weigh here on earth 1500 Kgs.
On the moon that same car will weigh (approx.) 400 Kgs.

The answer is therefore not 1500 Kgs, but : "There is no kind of universal car that weighs 1500 Kgs".

Success with your homework. Did you know there is a specific homework board for that?

I'm not buying your answer.

Weight is a funny term. Comes from f=ma. F is the force or the weight. A is the acceleration due to gravity at 9.8 m/sec^2.

f is in Newtons. The newton is the unit of force derived in the SI system; it is equal to the amount of force required to give a mass of one kilogram an acceleration of one meter per second squared.

In the English system, the unit of mass is the slug.

kg is a unit of mass. The mass is unaffected by gravity.

You can give your answer in Newtons or lbs.
Notice I didn't do the problem.
