Abicycle tire is spinning counterclockwise at 2.70 rad/s. during a time period at 1.90 s, the tire is stopped and spun in the opposite (clockwise) direction also at 2.70 rad/s. calculate the change in the tire's angular velocity aw and the tire's average angular acceleration aav. (indicate the direction with the signs of your answers.)
(a) the change in the tire's angular velocity aco (in rad/s) rad/s
(b) the tire's average angular acceleration aav (in rad/s2) rad/s
the answer is (a) the movement of the magnet relative to the coil
that is probably false!
have a goed day
the quickest, easiest, and most direct way to handle that kind of motion involves the use of the sine and cosine. but if you wanted to show off, you could do it with the secant and cosecant too.
