A water balloon is dropped from the top of a 200m high tower. An alert archer at the base of the tower sees the balloon being dropped, waits for 5.0s, then shoots an arrow at 40m/s straight up toward the balloon. How far has the balloon fallen when it is struck by the arrow? Make a diagram labelling all relevant information. As there are two objects involved in the problem create a table with columns and rows for each kinematic variable.

help this problem please!
