calculate the range of the projectile using the initial speed and angle. use 9.8m/s. Initial speed 18m/s and the is 75 degrees. I came up with 8.29 is that right

At the max. height, Vf = o.

Vf^2 = Vi^2 + 2gah = o,

(18)^2 + 2*(-9.8)h = 0,

324 - 19.6h = 0,

-19.6h = -324,

h = -324 / -19.6 = 16.5m = Range.

Your ans. is twice mine; check your math for error.
