At t 2, the angular velocity is zero, with a non-zero (positive) angular acceleration. At that time, the direction of rotation for BC is changing from CW to CCW. In summary, you should never assume ...

Using a stopping distance of 3 cm and a terminal velocity of 20 m/s gives an acceleration of 6666 m/ 2 or 680 g’s. If I use a terminal velocity of 12.2 m/s, the stopping acceleration goes down ...

If this net force was not zero, the vertical velocity would change. ... From this, I can calculate the average acceleration (during this interval) to get a value of 3.09 m/s 2.

If you were to feel the speed and not the velocity of a plane or car, that would be really, really weird, considering that the car is only going along at 110 kilometers per hour (68 miles per hour ...
