question 112

Short Answer

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?
