Question
At t =0s, a wheel rotating about a fixed axis at a constant angular acceleration of -0.40rad/s 2 has an angular velocity of 4rad/s and
At t=0s, a wheel rotating about a fixed axis at a constant angular acceleration of -0.40rad/s2 has an angular velocity of 4rad/s and an initial angular position of 0rad.
i) What is the angular position of the wheel at t=8.0s? How many rotations did the wheel make during 8s?
ii) At what time does the wheel momentarily comes to a stop?
iii) What is the angular position of the wheel at t=16.0s? How many rotations did the wheel make during 16s?
iv) What is the total number of rotations the wheel made during 20s?
