Homework Statement
Somehow Larry got stuck in the middle of a room with a frictionless floor. Larry is at rest. How could Larry start moving to get to the edge of the room?
A. Push on the floor with his hands or feet. That way the floor could exert a force on him and Larry could accelerate from rest to moving linearly.
B. Push on the floor with his hands or feet. That way the floor could exert a torque on him and Larry could accelerate from rest to rotating.
C. Spit. It's gross, but since momentum is conserved, Larry could gain an the same amount of momentum as the initial momentum of his spit.
D. Spit. It's gross, but since force is conserved, Larry could accelerate.
E. Spit. It's gross, but since momentum is conserved, Larry would have the same speed as his spit.
