A stick of mass F is lying on a frictionless surface. A small ball of mass G and velocity v collides with the stick in the center of the stick a right angle to the rod. The collision is elastic.
a) Where is the axis of rotation for the rod after the collision?
b) What is the angular velocity around the axis of rotation after this collision?
c) What is the velocity of the center of mass of the rod after the collision?
You're carrying a 3.2-m-long, 25 pole to construction site when you decide to stop for a rest. You place one end of the pole on a fence post and hold the other end of the pole 35 from its tip. How much force must you exert to keep the pole motionl..
