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

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

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
