The angular position of a point on the rim of a rotating, Ask an Expert

Academics

The angular position of a point on the rim of a rotating wheel is given by ?=4.0t- 3.0t2 + t3, where ? is in radians if t is given in seconds.

What is the angular velocity at t = 4.1 s?

What is the angular velocity at t = 5.6 s? What is the average angular acceleration for the time interval that begins at t = 4.1 s and ends at t = 5.6 s ?

What is the instantaneous angular acceleration at the beginning of this time interval?

What is the instantaneous angular acceleration at the end of this time interval?
