A girl throws the ball with horizontal velocity `2m//s` at the moment `t=0`. The ball bounces once on the smooth floor and then lands into cup `C`. The coefficient of restitution for the collision is `0.8`. Select the correct alternative `(g=10m//s^(2))`

A

The time taken by the ball to reach `B` is `sqrt((3)/(10))s`

B

The time taken by the ball to reach `C` is `2.6sqrt((3)/(10))s`

C

The ratio `(OC)/(OB)=2.6`

D

The distance `d` is `(52sqrt(3))/(10sqrt(10))m`
