Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a
100 kg ball traveling at 5 m/s.
A 1,000 kg ball traveling at 5 m/s would have
kinetic energy
A 10 kg ball traveling at 5 m/s would have
kinetic energy
A 100 kg person falling at 5 m/s would have
kinetic energy.
Intro
Done

Change in kinetic energy compared to a 100 kg ball travelling at 5 m/s

A 1,000 kg ball traveling at 5 m/s -    11250 J

A 10 kg ball traveling at 5 m/s-  1125 J

A 100 kg person falling at 5 m/s -    0 J

Explanation:

We have to initially calculate the kinetic energy of a 100 kg ball travelling at 5m/s.

calculating the kinetic energy of a 1000 kg ball travelling  at 5 m/s

difference in kinetic energy=12500-1250=11250 J

calculating the energy of 10 kg ball travelling at 5 m/s

difference in kinetic energy=1250-125=1125 J

calculating the kinetic energy of a 100 kg person falling at 5 m/s

difference in kinetic energy=1250-1250=0 J

A 1,000 kg ball traveling at 5 m/s would have 10 times more

kinetic energy

A 10 kg ball traveling at 5 m/s would have 10 times less

kinetic energy

A 100 kg person falling at 5 m/s would have The Same

kinetic energy.
