A motorized wheel is spinning with a rotational velocity of = 1.81 rad/s. At t = 0s, the operator switches the wheel to a
higher speed setting. The rotational velocity of the wheel at all subsequent times is given by
w (t) = warctan (c + bt²)
where c = 1.5574 and b = 6.53 s^-2.
At what time famax is the rotational acceleration at a maximum?
Tamax =
What is the maximum tangential acceleration a, of a point on the wheel a distance R = 1.25 m from its center?
What is the magnitude of the total acceleration of this point?
