### Question

A ball is thrown horizontally from a height with a certain initial velocity at time t = 0. The ball bounces repeatedly from the ground with the coefficient of restitution less than 1 as shown. A Ball is Thrown Horizontally In figure a ball is thrown horizontally from a height with a certain initial velocity at time t = 0 is shown.

Neglect air resistance and taking the upward direction as positive, which figure qualitatively depicts the vertical component of the balls velocity (VY) as a function of time (t)?

### Choices

Choice (4) Response

a. Graph of Component of Velocity Vy ⟶ Time T (Choice A) Figure represent plot of component of velocity of ball (Vy) ⟶ time (t)

b. Graph of Component of Velocity Vy ⟶ Time T (Choice B) Figure represent plot of component of velocity of ball (Vy) ⟶ time (t)

c. Graph of Component of Velocity Vy ⟶ Time T (Choice C) Figure represent plot of component of velocity of ball (Vy) ⟶ time (t)

d. Graph of Component of Velocity Vy ⟶ Time T (Choice D) Figure represent plot of component of velocity of ball (Vy) ⟶ time (t)
