Two blocks are connected by a compressed spring,
held with a string. They move at speed v over an
icy pond. After the string is cut, block A
stops. What is the speed of block B, if
mAmB? A 0 B v C 2v D 3v E none of these
What is the speed of block B, if mA 2mB?
D

If mA 2mB, what is vA/vB in the center of mass
reference frame?
A 1/2 B 1 C 2 D 4 E none of these
In the center of mass reference frame shown, what
is the velocity of mB after the collision, if it
is completely elastic? A 0 B vA to the
right C vA left D vB to the right E vB left
