Constant Angular Acceleration: In the figure, point P is on the rim of a wheel of radius 2.0 m. At time t = 0, the wheel is at rest, and P is on the x-axis. The wheel undergoes a uniform counterclockwise angular acceleration of 0.010 rad/s2 about the center O.(a) At time t = 0, what is the tangential acceleration of P?(b) What is the linear speed of P when it reaches the y-axis?(c) What is the magnitude of the net linear acceleration of P when it reaches the y-axis?(d) How long after starting does it take for P to return to its original position on the x-axis?
What will be an ideal response?
(a) 0.020 m/s2 (b) 0.35 m/s (c) 0.066 m/s2 (d) 35 s
