Question
Which of the following statements is true regarding a bowling ball and a ping-pong ball being dropped from the Eiffel Tower?Group of answer choicesWhen they both reach terminal velocity, they have the same velocity.The bowling ball accelerates more than the ping-pong ball.The ping-pong ball reaches terminal velocity first.The ping-pong ball experiences more air resistance.
Solution
The statement "The ping-pong ball reaches terminal velocity first" is true.
Here's why:
-
Terminal velocity is the maximum constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration. This happens when the force due to gravity is equal to the drag force acting on the object.
-
A bowling ball and a ping-pong ball dropped from the Eiffel Tower will both experience the force of gravity pulling them down. However, the ping-pong ball, being much lighter and less dense than the bowling ball, will experience a greater effect from air resistance.
-
As the ping-pong ball falls, it quickly reaches a point where its weight is balanced by the air resistance. This is when it reaches its terminal velocity.
-
On the other hand, the bowling ball, being heavier, will continue to accelerate for a longer period before the air resistance can balance its weight. Therefore, it will reach its terminal velocity later than the ping-pong ball.
So, the statement "The ping-pong ball reaches terminal velocity first" is true.
