Question Reads: " A passenger in a hot air balloon throws a ball with an innitial unknown velocity. the ball accelerates at 9.8m/s down for 2.0s. at which time its instantenous velocity is 24m/s [45 below the horizontal]. determine the balls innital velocity "

2. Relevant equations

vf = vi + at

3. The attempt at a solution

ok, these kinds of problems are very new to me.

i made vf = 24sine45 since we are only discussing the y direction speed.

and vi = visinetheta.

but the answer says 17m/s [10 degress above horizontal]

where did 17 come from along with the angle ? please guide me
