As shown in Fig 1. A wheel of radius .1 m and mass kg is rolling (i.e. no slip between the wheel and the surface) back and forth on a circular surface of radius m. At the time when wheel reaches the bottom, the velocity of the mass center is v= 0.05 m/s potting horizontally to the right. Calculate the following:
A) Respective velocities of points A (bottom of the wheel), B (top of the wheel) and C (rearmost point of the wheel).
B) Respective accelerations of points A, B and C on the wheel as indicated.
