45π - 19π - 35π = -28.3rad/s
45π - 19π + 35π = 192radrad/s
Two identical tops spin with angular velocities 45π rad/s up and 19π rad/s down, respectively, about vertical axes on a table. The tops bump into one another and separate. After the collision, one of the tops has an angular velocity of 35π rad/s in its original direction.
What is the angular velocity of the other top if the 45π rad/s top ends up with the angular velocity of 35π rad/s? (Answer: -28.3rad/s)
What is the angular velocity of the other top if the 19π rad/s top ends up with the angular velocity of 35π rad/s? (Answer: 192rad/s)
