Required: Torque motor must supply to take the disk from 0 to 1800 rpm in 4.0 s? EF 152 Fall, 2008 Lecture 7-1 3 Given: Just after leaving the platform, the diver's fully-extended 80-kg body has a rotational speed of 0.3 rev/s about an axis normal to the plane of the trajectory. Required: Determine the angular velocity later in the dive when the diver has assumed the tuck position. Approximate the man as a solid rod in the fully extended position and a solid sphere in the tuck position. 0.7 m
