Are frozen water balloons more dangerous than un-frozen water balloons of the same mass and hurled at the same speed? Explain your answer. (a) Yes. Since they are more likely to bounce off the target and therefore experience a greater change of momentum, frozen water balloons would impart a greater force. (b) Yes. Since they are more rigid and therefore take less time to change momentum upon impact, frozen water balloons would impart a greater force. (c) Yes, for both of the reasons described above. (d) No. Since they have the same mass and speed, their momentum and energies are the same; so it makes no difference if they're frozen or not. (e) Other: 3.

Hello I need help finding the solution for this question. Please and thank you.
Transcribed Image Text:Are frozen water balloons more dangerous than un-frozen water balloons of the same mass and hurled at the
same speed? Explain your answer.
(a) Yes. Since they are more likely to bounce off the target and therefore experience a greater change of
momentum, frozen water balloons would impart a greater force.
(b) Yes. Since they are more rigid and therefore take less time to change momentum upon impact, frozen
water balloons would impart a greater force.
(c) Yes, for both of the reasons described above.
(d) No. Since they have the same mass and speed, their momentum and energies are the same; so it makes
no difference if they're frozen or not.
