1 a (for a non-conductive nearby surface)
2 d
3 b (if referring to the person “having” the kinetic energy of the ball. The person has (a) which can be used to roll down the hill.
4 b
5 all of those are used for the purpose
Song -
Those windshield wipers slappin’ out a tempo
Keepin’ perfect rhythm with the song on the radio

Driving My Life Away Eddie Rabbit
From the movie Roadie, if I remember right

  1. A
  2. B
  3. C. (To explain my answer. The ball itself has Potential energy at the top of the hill. The ball itself has Kinetic energy when rolling down the hill. But the Person has Thermal energy at the top of the hill, ball or no ball.)
  4. C
  5. B

1- a) Incident energy
2- b) activate the trip signal to open the contacts
3-a&c) The timing of the ball toss has nothing to do with it. The Boy’s gravitational potential energy equals his mass times the height of the hill times the force of gravity. (PE=mass x height x g)

Everybody has thermal energy (aka heat energy). It is the energy possessed by an object due to the movement of particles within the object. (Q= mass x temperature x specific heat)
4-c) Interrupt the current flow
5-d) Air circuit breakers (either magnetic or compressed air) are currently preferred to oil circuit breakers

So… … …
It was pretty close with great responses.
I’m probably gonna get in trouble with Joe & Bert with their
extensive experience & knowledge.
Hope to see you all next time :cowboy_hat_face:

Congrats to Ryan Uecker & Jim Gilbert for the win!

Eddie Rabbit “Driving My Life Away”

Edward Thomas Rabbitt was an American country music singer and songwriter. His career began as a songwriter in the late 1960s, springboarding to a recording career after composing hits such as “Kentucky Rain” for Elvis Presley in 1970 and “Pure Love” for Ronnie Milsap in 1974.

Thanks Mark!

Just a few words if I may…

I have to thank my family for their enduring support, my friends, my fellow inspectors, the Academy, the Rewards Committee, InterNACHI, and countless others. But most of all, I have to thank Google. For being there when I needed them, for correcting my spelling when I type search terms wrong, for not judging me by some of the stuff I search :wink:. Thank you Google.
