Compute all parts of given question:

Question: To light the Olympic flame, an archer shoots and arrow into the air toward the cauldron where the flame is to be ignited. The archer stands 150 meters from the base of the cauldron and the cauldron is 50 meters high. Four seconds after it is released, the arrow hits the cauldron and the flame is ignited. Assume the arrow is released from groundlevel.

Part A: What are the initial magnitude and direction of the velocity of the arrow as it leaves the bow?

Part B: With what velocity (magnitude and direction) does the arrow strike the cauldron?

I need help to find the initial magnitude and direction of the velocity of the arrow as it leaves the bow.
