Question Let the initial state represent the instant the balls are released and the final state represents the instant the balls reach the far-right side. Both balls have identical initial and final vertical positions. The total mechanical energy of the foreground ball is
E_(F,B,)=K_(F,B,) U_(F,B,)
and the total mechanical energy of the background ball is
E_(B.B.)=K_(B.B.) U_(B.B.)
. Which relationship correctly relates the energy of the two balls? Assume friction is negligible.
E_(F.B.)>E_(B.B)
E_(F.B.)=E_(B.B)
E_(F.B.)
