# Video Discussion: Tangential Acceleration Introduction with Example Problem - Mints on a Turntable

## Recommended Posts

Name: Tangential Acceleration Introduction with Example Problem - Mints on a Turntable
Category: Rotational Motion
Date Added: 2017-08-13
Submitter: Flipping Physics

Tangential Acceleration is introduced and visualized. Example problem is worked through. We even relate arc length, tangential velocity, and tangential acceleration via the derivative! Example: A record player is plugged in and uniformly accelerates to 45 revolutions per minute in 0.85 seconds. Mints are located 3.0 cm, 8.0 cm, and 13.0 cm from the center of the record. What is the magnitude of the tangential acceleration of each mint?
Want Lecture Notes? This is an AP Physics 1 topic.
