Asked by Joe
A bullet of mass m travelling at speed vo in the direction shohwn above strikes a block of mass M and embeds itself in it. The block is sitting on the edge of a frictionless table of height H and is knocked off of the table by the collision.
a) What is the speed vb of the block immediately after the bullet sticks?
b) What distance R from the base of the table does the block land?

How long does it take to fall height H? figure that.
then,
distance=velocity*timefalling
solve for velocity
then,
distance=velocity*timefalling
solve for velocity
