Three balls are launched from the top of a building of height H. The balls m₁ and m₂ are launched with the same initial speed Vo with m₁ making an angle of 45^o above the horizontal and m₂ launched horizontally (i.e. 0 degrees to the horizontal); m₃ is dropped straight vertically down from rest.

If m₃>m₂>m₁ what will be the correct relationship between their final speeds when they hit the ground level (base level of the building)?

Assume air resistance is negligible

Correct answer (V1=V2)>V3... confused as to why
