A ball is shot from the ground into the air. At a height of 9.1 m, the velocity is observed to be v = (6.8 i + 7 j) m/s, with i horizontal and j upward.

(a) To what maximum height does the ball rise?

1 m

(b) What total horizontal distance does the ball travel?

2 m

(c) What is the magnitude of the ball's velocity just before it hits the gound?

3 m/s

(d)What is the direction of the ball's velocity just before it hits the ground?

4Â° relative to the horizontal
