The angular speed of a point following a circular path with radius r = 0.188 m can be described by the equation: W = 7.07t + 6.26 rad/s. Part 1) Write an expression for the angular acceleration of the point. CKE rad/s Part 2) Between t = 1.05 s and t = 2.37 s, what total angle is the point displaced through? radians Part 3) At t = 1.05 s, what is the magnitude of the translation acceleration? a = m/s
