During a fireworks display, a shell is shot into the air with an initial speed of 98.8 m/s at an angle of 71.9° above the horizontal, as illustrated in Figure. The fuse is timed to ignite the shell just as it reaches its highest point above the ground. Calculate the height at which the shell explodes. Enter your answer in meters using 3 significant figures. h= 233 m - 75 X= 125 m
