I keep getting the wrong answer! For this question, I'm getting 4.70 m...can someone tell me what i'm doing wrong?(adsbygoogle = window.adsbygoogle || []).push({});

A ball is thrown from a point 1.2m above the ground. The initial velocity is 19.2m/s at an angle of 30 degrees above the horizontal. Find the maximum height of the ball above the ground.

I'm taking the (initial velocity multiplied by sin 30)^2 / 2*9.8 which is 4.70...but it's not correct. What am i doing wrong?
