Answer 2

Option (a) is correct

Explanation:

• Considering Newton's mechanics , we know that , F= ma , where , F is the force applied on an object , m is the mass of the object  and a is the acceleration.
• Therefore if mass of the object is greater like in case of the bowling ball here , then for the same force applied , the acceleration will be less making the speed less and hence it would tend to travel a shorter distance.
• Also when the mass of the object is more , it has more inertia and therefore greater tendency to resist changes in the state of motion. This causes the object to travel shorter distance .
• Here ,  tennis ball will have less inertia due to lesser mass as compared to the bowling ball and hence moves farther away.
• Option (a) is therefore correct.
