A particle is rotating about a fixed axis with an initial angular velocity magnitude of 0.260 rev/s. The magnitude of the angular acceleration is 0.901 rev/s2. Both the angular velocity and the angular acceleration are directed counterclockwise. The particle is 0,380 mm from the fixed axis. a) Compute the particle's angular velocity magnitude after time 0,201 s has passed. b) Through how many revolutions has the particle turned in the time interval 0.201 s from Part A? c) What is the tangential speed vt of the particle at time t = 0.201 s? d) Calculate the magnitude at of the tangential acceleration of the particle at time t = 0.201 s. e) Calculate the magnitude ar of the radial (or centripetal) acceleration of the particle.
