Help finding the maximum height

[SalsaOnMyTaco]

hi guys. new here, i need help finding the maximum height, i saw my question was posted before here

Ted Williams, Professor Emeritus of Hitting with the Boston Red Sox, visits the Skydome in Toronto where all distances are measured in meters. He demonstrates to the younger Bluejays how it is done by hitting a home run that clears a low fence 120 m from home plate.

d) For these same conditions, find the maximum height (relative to the top of the fence) reached by the ball on its trajectory.
ymax = m

i am still confused and not able to do the problem

to find the maximum height of a projectile the formula needed is

ymax=v_Isin2Ө_i/2g
