A ball is shot from the ground into the air. At a height of 9.1 m, the velocity is observed to be v = (7.9 i + 6.9 j) m/s, with i horizontal and j upward.
(a) To what maximum height does the ball rise?
11.5136 m
(b) What total horizontal distance does the ball travel?
m
(c) What is the magnitude of the ball's velocity just before it hits the gound?
m/s
(d) What is the direction of the ball's velocity just before it hits the ground?
° relative to the horizontal
I got A
I don't really know how to start B.. could someone give me a hint?
