To determine

The correct option for the statement "A batted baseball soaring through the air with negligible air resistance has".

Answer to Problem 2RAT

The correct option for the statement "A batted baseball soaring through the air with negligible air resistance has" is option (a).

Explanation of Solution

Force is defined as the amount of work done on an object to move it to a specific distance. It can be calculated through Newton's relation of force, mass, and acceleration. Force is not that a body can possess, it comes into existence only when one body comes in contact with another body. Force comes in action when some external means act on the body.

In case of the speeding ball, the ball interacts with air only, but air resistance is given as zero in magnitude. Therefore, there is no interaction present on the ball.

Conclusion:

Therefore, the correct option for the statement "A batted baseball soaring through the air with negligible air resistance has" is option (a).
