The angular position of a point on a rotating wheel is
Chapter , Problem 4(choose chapter or problem)
The angular position of a point on a rotating wheel is given by u ! 2.0 & 4.0t2 & 2.0t3 , where u is in radians and t is in seconds.At t ! 0, what are (a) the points angular position and (b) its angular velocity? (c) What is its angular velocity at t ! 4.0 s? (d) Calculate its angular acceleration at t ! 2.0 s. (e) Is its angular acceleration constant?
