Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a50 kg ball traveling at 10 m/s.
Answers:
A 50 kg ball traveling at 20 m/s would have kinetic energy.:4 times more
A 50 kg ball traveling at 5 m/s would have kinetic energy.:4 times less
A 50 kg person falling at 10 m/s would have kinetic energy.:the same
