Chapter 2, Problem 18Q

To determine

To explain: Whether the result will be altered if air resistance is considered for the given situation.

Answer to Problem 18Q

Yes, result will alter. Air resistance will reduced the speed of ball.

Explanation of Solution

Introduction:

Air resistance: The opposing force of air which slows down the velocity of object coming down.

When an object is thrown upward the velocity of object is V₁ and when the object is come downward with air resistance is V₂ so when air resistance is applied on the object than its velocity will decrease as acceleration due to air resistance will oppose the motion and decrease the velocity of object.

So,

  $V_1>V_2$

Conclusion:

Air resistance will reduced the speed of ball.
