       Average speed = (1/2) (beginning speed + ending speed)

                               = (1/2)        ( 13 m/s  +  30 m/s )

                               =    (1/2)        ( 43 m/s )

                               =        21.5 m/s

erma4kov [3.2K]

Answer: 1: kinetic energy and velocity are at zero when the magnets are held apart, and both increases rapidly when they are released and move together. Energy stored in the magnetic field decreases.

2: The energy stored in the system is converted to kinetic, thermal, and sound energy.

3: The energy stored in the magnetic field does not change.

4: Some of the energy stored is converted into kinetic and thermal energy.

5: Two small repelling magnets hold each other in place.

Just took the quiz all are correct! I hope this helps you! :)
