I can hear a sound and give the frequency. I have good master tuning.

I was wondering how will I ever understand the derivation of the formulas. Thank you!
By Jamal TischlerAugust 18, 2015
It will move to the left relative to the truck. The acceleration a to the left is the fictional or inertial acceleration and that means that is relative to the truck. There are 2 diffrent accelerations a in opposite directions and they cancel, if we discuss relative to the ground.
