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

iron would move it is magnetic there is a mag field around the current in the wire

im guessing the west of station b
