If two balls of same masses are dropped on sand, the depths of penetration is same if The product /(mv/) is same for both bodies. Hence, the correct option is (c).
Q. Will a heavier ball roll farther than a lighter ball?
The heavy one would only roll farther if they had the same acceleration. OP said that the two balls are pushed with the same energy (I assume he means force). If you use to same amount of energy to push both balls, the lighter ball would roll much farther, factoring in friction and air resistance.

Q. Are all spontaneous process irreversible?
Spontaneous processes are irreversible. Like total energy, E, and enthalpy, H, entropy is a state function. The second law of thermodynamics states that the entropy of the universe increases for spontaneous processes, and the entropy of the universe does not change for reversible processes.
Q. Will two objects hit the ground at the same time?
In other words, if two objects are the same size but one is heavier, the heavier one has greater density than the lighter object. Therefore, when both objects are dropped from the same height and at the same time, the heavier object should hit the ground before the lighter one.
Q. Why does a feather fall slower than a brick?
Well, it’s because the air offers much greater resistance to the falling motion of the feather than it does to the brick. The air is actually an upward force of friction, acting against gravity and slowing down the rate at which the feather falls.
Q. Which will hit the ground first?
Q. Which falls faster an egg or a watermelon?
The correct answer is the last one: the two will hit the ground at the exact same time. This is because gravity accelerates all objects equally, even if one object is heavier than the other. The watermelon also has a lower acceleration because it is heavier and the egg the opposite.
Q. Why does a feather reach the ground after the hammer?
This is because the feather reaches it’s terminal velocity quicker, because its air resistance increases as it falls. The hammer is much heavier, so it travels faster, before air resistance is large enough to balance its weight.
Q. Who dropped a feather and a hammer together to see if gravity pulled on them the same amount?
Commander David Scott
Q. Does gravitational force exist in vacuum?
Yes, gravity does exist in a vacuum. A vacuum does not need to be completely devoid of matter, it just needs to have a lower pressure than the area around it.
Q. Does Weight exist in a vacuum?
The answer is because they are in free fall. In a vacuum, gravity causes all objects to fall at the same rate. The mass of the object does not matter. If a person drops a hammer and a feather, air will make the feather fall more slowly.
Q. What is the value of g in vacuum?
Free Falling Object. the value of g is 9.8 meters per square second on the surface of the earth. The gravitational acceleration g decreases with the square of the distance from the center of the earth.
Q. Why weight is maximum in vacuum?
In vacuum, there is no force of buoyancy, therefore weight is maximum in vacuum.
