A motorized wheel is spinning with a rotational velocity of a, = 1.81 rad/s. At t 0 s, the operator switches the wheel to a higher speed setting. The rotational velocity of the wheel at all subsequent times is given by w (1) = ayarctan (e + bi") where e= 1.5574 and b = 5.21 s-2. At what time tmas is the rotational acceleration at a maximum? Temax= 358.30 ms What is the maximum tangential acceleration a, of a point on the wheel a distance R= 1.11 m from its center?

A wheel of radius 75cm is rotating with a frequency of 3.0Hz about a fixed axis of rotation. What is the speed of a piece of chewing gum stuck to the rim?

A disk spins at 4.0 revolutions/second. What is its period, in second? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

A child is riding their bicycle.  The rear wheel is spinning at an angular velocity of 193.35 rpm and they apply the brakes and stop in 3.695 s. How many revolutions did the wheel go through before it stopped?

A motorized wheel is spinning with a rotational velocity of @= 1.73 rad/s. At t=0 s, 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) = woarctan (c + b₁²) where c= 1.5574 and b = 5.87 s-2. At what time famax is the rotational acceleration at a maximum? tamax a₁ 0.338 What is the maximum tangential acceleration a, of a point on the wheel a distance R = 1.27 m from its center? Incorrect a= 5.03 Incorrect What is the magnitude of the total acceleration of this point? 5.21 ms m/s2 m/s²
