Question
A ball is dropped on a floor and bounces back to a height somewhat less than the original height, which of the curves depicts its motion correctly?
The correct answer is:
When a ball is dropped on a floor then
So, the graph between 
is a parabola. Here 
decrease as time decrease. When the ball is bounces back then
Eq. (ii) is also the form of a general equation of parabola so the graph between will be a parabola. Here increases when the time increases. Hence, the required graph between is shown in the figure.
