Figure 0.1 -0.01 rad/s2 Point P is on the rim of a wheel of radius 2.0 m. At time t = 0, the wheel is at rest, and Pis on the x-aus. The wheel undergoes a uniform angular acceleration of g.01 rad/s2 about the center O In Figure 9.1, the tangential acceleration of P at time t = 0 sis closest to: O A. 0.010 m/s? O B. 0.015 m/s2 OC.o.005 m/s? O D.0.020 mis? O E. zero

A yo‑yo with a mass of 0.0850 kg and a rolling radius of r=1.60 cm rolls down a string with a linear acceleration of 5.20 m/s2. Calculate the tension magnitude ? in the string and the angular acceleration magnitude ? of the yo‑yo.

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.

W L A rod of length L = 35.0 cm rotates about its end through O with a constant angular acceleration a = 2.23 rad/s², as shown in the figure.
