A. 0.03 [m/s] C. 33.3 [m/s] B. 8.66 [m/s] D. 75.0 [m/s]I need help with this questionMacmillan l A motorized wheel is spinning with a rotational velocity of wo = 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) = woarctan (c + b1²) where c = 1.5574 and b = 6.09 s-². At what time tamax is the rotational acceleration at a maximum? tamax = What is the maximum tangential acceleration a, of a point on the wheel a distance R = 1.29 m from its center? a₁ = What is the magnitude of the total acceleration of this point? a = ms m/s² m/s²
- A solid 0.6150 kg ball rolls without slipping down a track toward a vertical loop of radius ?=0.7350 m. What minimum translational speed ?minvmin must the ball have when it is a height H=1.111 m above the bottom of the loop in order to complete the loop without falling off the track? Assume that the radius of the ball itself is much smaller than the loop radius ?R. Use g=9.810 m/s^2 for the acceleration due to gravity.A bucket ( m = 4.0 kg ) is falling down to a 25 meter deep well as shown in the figure.
