Mass M moves to the right with speed =v along a frictionless
horizontal surface and crashes into an equal mass M initially at
rest. Upon colliding, the two masses stick
together and move with speed V to the right.
Notice that v and V denote different
speeds. After the collision the magnitude of
the momentum of the system is:

A physics student playing with an air hockey table (a
frictionless surface) finds that if she gives the puck a velocity
of 3.78 m/s along the length ( 1.79 m ) of the table (the
x-direction) at one end, by the time it has reached the other end
the puck has drifted a distance 2.55 cm to the right (the
y-direction). The puck still has a x-component of its velocity of
3.78 m/s when it reaches the other end of...

A thin rod (mass 8.28 kg, length 8.04 m) is sitting on a
horizontal, frictionless table. There is a 0.626 kg frog sitting on
the very end of the rod; you can treat the frog as a point
particle. Suddenly the frog jumps off at speed 4.75 m/s, moving
horizontally and perpendicular to the rod. Find ω, the angular
speed of the rod after the frog jumps off, in rad/s.
