# A little help?

#### krazee

alright, i've been workin on this problem for the last three hours...and so far i'm drawing a blank ...any help would be really appreciated:

Robin Hood is travelling by train through Sherwood Forest on this way to Nottingham, with a constant velocity of 20.0m/s . As he passes a crossroad he spies an evil knight resting beside his trusty Kawasaki at 300m [E] from the rail line. After taking 5.0seconds to load his bow, Robin shoots it from the train with a horizontal speed of 50.0m/s (we can ignore the fact that he shot the arrow at 45 degrees above the horizontal). Determine the velocity (horizontally)of the arrow along the path from Robin to the knight, and the direction in which Robin has to aim to take into account the train's motion.
