Question
Read through the and calculate the predicted change in kinetic energy of the oblect compared to 50 kg ball traveling at 10 m/s . 50 kg ball traveling at 20 n / s would havekinetic energy 50 kg traveling at 5 m/s would have energy 50 kg person falling at 10 m/s would havekinetic energy

Answer:
7500 J
-2475 J
0 J
Explanation:
Kinetic energy, KE is given by
where m is the mass of an object and v is the velocity.
Change in kinetic energy is calculated by
First case
We compare 50 kg travelling at 10 m/s to 50 kg at 20 m/s
Second case
We compare 50 kg travelling at 10 m/s to 50 kg at 5 m/s
Third case
We compare 50 kg travelling at 10 m/s to 50 kg at 10 m/s
