Consider a rubber ball freely falling from a height h=4.9 mh=4.9 \mathrm{~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 the height as function of time will beConsider a rubber ball freely falling from a height h=4.9 ~m onto a horizontal elastic plate.

Options

  1. AWhat is the electronic configuration of hydrogen?
  2. BWhat is the electronic configuration of hydrogen?
  3. CWhat is the electronic configuration of hydrogen?
  4. DWhat is the electronic configuration of hydrogen?

Correct answer

C. What is the electronic configuration of hydrogen?

Step-by-step solution

h=12gt2,v=−gt\mathrm{h}=\frac{1}{2} \mathrm{gt}^2, \quad \mathrm{v}=-\mathrm{gt} and after the collision, v=gt\mathrm{v}=\mathrm{gt}. (parabolic) (straight line) Collision is perfectly elastic then ball reaches to same height again and again with same velocity.
