You drop a package from a plane flying at constant speed in a straight line. Without air resistance, the package will:
|
|
quickly lag behind the plane while falling
|
|
|
remain vertically under the plane while falling
|
|
|
move ahead of the plane while falling
|
|
|
not fall at all
|
Explanation:
Detailed explanation-1: -Ans : (B) Remain vertically under the plane while falling.
Detailed explanation-2: -If there is no resistance, bomb will drop at a place exactly below the flying aeroplane. But when we take into account air resistance, bomb will face decceleration in its velocity. So it will fall on the earth exactly behind aeroplane. Was this answer helpful?
Detailed explanation-3: -As can be seen from the above animation, the package follows a parabolic path and remains directly below the plane at all times. As the package falls, it undergoes a vertical acceleration; that is, there is a change in its vertical velocity.
