Question
The figure shows six identical balls that are thrown off cliffs. All the cliffs are the same distance above the ground, and the ground below each cliff is level. The figures show the initial velocity of each ball. For case F, the speed of the ball is v = 6·m/s. Ignore air resistance. For each of the following ranking tasks use the symbols > and = to indicate your ranking (ties are possible), listing any that are equal in alphabetical order. For example, if Y and Z are the same and are both greater than X, then you would enter Y=Z>X (note: Z=Y>X would be incorrect, since Y and Z, being equal, must be in alphabetical order).
Explanation / Answer
Kinetic energy C>E>F>B=D>A Potential Energy A=B=C=D=E=F mechanical Energy (Kinetic+Potential) C>E>F>B=D>A speed (all balls will have zero potential energy when they hit the floor, then the largest speed will have the ball with graeter mechanical energy) C>E>F>B=D>A
