Three identical balls are thrown from the top of a building, all with the same initial speed. As shown in figure., the first ball is thrown horizontally, second above horizontal level, and third at an angle below the horizontal. Neglecting air resistance, rank the speeds of the balls at the instant each hits the ground.

A

`v_(A)=v_(B)=v_(C)`

B

`v_(A)=v_(B)gt v_(C)`

C

`v_(B)gtv_(C)gtv_(A)`

D

`v_(A)gtv_(B)=v_(C)`
