Just confused a little bit as to where to start. Can the 50 m also be the Range of the ball? And if that is so, can you use that to find v2, because the ball is falling at a constant of 9.81 m/s^2...and then you could say that Ryan runs the same velocity as the ball but in the opposite direction...is this wrong? I need a little push in the right direction!
Find out where the ball lands.
time in air:
hfinal=viy*t -1/2 g t^2
where vi=21*sin41, and hfinal=0
solve for time in air.
Then, distance:
x= vix*timeinair where vix=21cos41
Now you know where the ball will land.
Ryan has to start at 51m point, which direction does he run?
