hmmm, i tried that and still got answer wrong, these were my steps
100t-86.6t=600, therefore t=44.78
then i plugged t=44.78 into y=1/2gt^2+vsinθt +H (with v=100 and θ =30)
since we have the time of flight the value of y will be zero leading to the only unknown being H.
Thanks

This seems too hard. Wouldn’t the time of flight be different for each projectile??

For both balls we have





Solve and to get the time of flight for each ball (call these and ).

Obviously the ball shot straight horizontally will hit the ground sooner (and will travel less), so you need to solve

(not the other way around!)

for .

I calculated .
