A rugby player passes the ball 6.78 m across the field, where it is caught at the same height as it left his hand. (Assume the player is facing the +x direction.)

Question

(a) At what angle (in degrees counterclockwise from the +x-axis) was the ball thrown if its initial speed was 12.1 m/s, assuming that the smaller of the two possible angles was used?
(° counterclockwise from the +x-axis)

(b) What other angle (in degrees counterclockwise from the +x-axis) gives the same range?
(° counterclockwise from the +x-axis)


(c) How long (in s) did this pass take?
