Consider a rubber ball freely falling from a height\[h=4.9\text{ }m\]onto a horizontal elastic plate. Assume that the duration of collision is negligible and the collision with the plate is totally elastic. Then the velocity as a function of time and the height as a function of time will be:
AIEEE Solved Paper-2009
A)
B)
C)
D)
Correct Answer:
C
Solution :
When ball strikes the surface its velocity will be reversed so correct option is (3).
