1. A motor gives gear A an angular acceleration of aA = (2 + 0.006 u2) rad> s2, where u is in radians. If this gear is initially turning at vA = 15 rad> s, determine the angular velocity of gear B after A undergoes an angular displacement of 10 rev.
2. A motor gives gear A an angular acceleration of aA = (2t3) rad> s2, where t is in seconds. If this gear is initially turning at vA = 15 rad> s, determine the angular velocity of gear B when t = 3 s.
