Vertical PROBLEM 15.7 When studying whiplash resulting from rear end collisions, the rotation of the head is of primary interest. An impact test was perfomed, and it was found that the angular acceleration of the head is defined by the relation a=700cos 0+70sin where a is expressed in rad/s“ and O in radians. Knowing that the head is initialy at rest, determine the angular velocity of the head when 6=30°.

PROBLEM 15.7
When studying whiplash resulting from rear end collisions, the rotation of the head is
of primary interest. An impact test was perfomed, and it was found that the angular
acceleration of the head is defined by the relation =700cos &+70sine where a is
4expressed in rad/s“ and ở in radians. Knowing that the head is initilly at rest,
determine the angular velocity of the head when 6= 30°.
