2. how much work does gravity do in causing a 6 kg hammer to fall to the ground from a
height of 10 m?

heavy objects will have a higher terminal velocity than light objects. ... It takes a larger air resistance force to equal the weight of a heavier object. A larger air resistance force requires more speed.) Therefore, heavy objects will fall faster in air than light objects.

are their multiple choices ?

explanation:

e/c, where e is its total energy
