B) Through how many revolutions has the blade turned in the time interval 0.201 s
C) What is the tangential speed v_tan (in m/s) of a point on the tip of the blade at time 0.201 s
D) What is the magnitude of the resultant acceleration (in m/s^2) of a point on the tip of the blade at time 0.201 s ?
This solution is provided in an attached .jpg file. It includes calculations for finding revolutions per second, angular velocity, and acceleration. A diagram is provided to enhance learning.
