Problem: A ball is shot from the ground into the air. At a height of 8.2 m, the velocity is observed to be v = (7.6)i + (5.3)j in meters per second (i horizontal, j upward).

Part A: What is the velocity of the ball (magnitude and direction) the instant before it hits the ground? That is what is its i-component?

Part B: What is its j-component?

Please use as much detail as possible in answer!
