(b)(ii) Use the graph to determine the acceleration of the car and Calculate the net force acting on the car to produce the acceleration found in part (b)(ii) .

Explanation:

We should understand that acceleration due to gravity does not affect the horizontal acceleration of the block, whether on earth or on the moon. On earth we use the following relationship to obtain the mass of the object.

The mass does not change whether on earth or on the moon. Mass is the quantity of matter contained in a body and it does not change with the location of the body. The same relationship between force, mass and acceleration also holds over there.

Therefore, on the moon;
