When studying whiplash resulting from rear-end collisions, the rotation of the head is of primary interest. An impact test was performed, and it was found that the angular acceleration of the head is defined by the relation a= 700 cos0 + 70 sin 0, where a is expressed in rad/s2 and 0 in radians. Knowing that the head is initially at rest, determine the angular velocity of the head when 0= 30°.
