If the car is on the moon, its mass is about 817 kg.

If it's on the Earth, its mass is about 135 kg.

Answer:

Mass of the car, m = 135 kg

Explanation:

The weight of the car is 1323 N. Let m is its mass. The relation between the mass and weight comes form Newton's second law of motion. We know that the weight of an object is the force that is exerted due to acceleration due to gravity.

The mathematical form of weight of an object is given by :

W = mg

g is the acceleration due to gravity

$m=\dfrac{W}{g}$

$m=\dfrac{1323\ N}{9.8\ m/s^2}$

m = 135 kg

So, the mass of the car is 135 kg. Hence, this is the required solution.

Answer You need to consider that the gravity on earth is 9.8 m/s/s. This means any object you let go on the earths surface will gain 9.8 m/s of speed every second. You need to apply a force on the object in the opposite direction to avoid this acceleration. If you are pushing something up at a constant speed, you are just resisting earths acceleration. The more massive and object is, the greater force is needed to accelerate it. The equation is Force = mass*acceleration. So for a 2kg object in a 9.8 m/s/s gravity you need 2kg*9.8m/s/s = 19.6 Newtons to counteract gravity. Work or energy = force * distance. So to push with 19.6 N over a distance of 2 meters = 19.6 N*2 m = 39.2 Joules of energy. There is an equation that puts together those two equations I just used and it is E = mgh

The amount of Energy to lift an object is (mass) * (acceleration due to gravity) * (height)

:Hence, the Work done to life the mass of 2 kg to a height of 10 m is 196 J. Hope it helps❤️❤️❤️
