Question
In the absence of air resistance, a ball thrown horizontally from a tower with velocity v, will land after time T seconds.
If, however, air resistance is taken into account, which statement is correct?

Solution
The correct option is A The ball lands with a horizontal velocity less than v after more than T seconds
In the presence of air resistance,
The ball lands with a horizontal velocity less than v after more than T second.
when air resistance acts acceleration during a fall will be less than g because air resistance affects the motion of the falling objects by slowing it down.
Air resistance depends on two factor.(I) speed of the object(II) surface area of the object.
Increasing the surface area of an object then speed will be decrease of the object
