At the position of terminal speed the net acceleration of the ball will become zero
As we know that terminal speed will always reach when net force on the ball is zero and its speed will become constant.
So here at this position we can say
now when ball is moving at half of the terminal speed in upward direction then net force on the ball in downwards direction will be
here speed of the ball is half of the terminal speed
then we have
now acceleration will be given as
now we have
downwards
Answer:
On the way back up the hill, the car converts kinetic energy to potential energy. In the absence of friction, the car should end up at the same height as it started. ... The total energy of the ball stays the same but is continuously exchanged between kinetic and potential forms.
