Your result turned out okay. However, you should avoid rounding intermediate values to the number of significant figures. Keep a few extra digits in intermediate values, and only round your results at the end. Otherwise, rounding/'truncation errors will creep into your significant figures by the end of the calculations.

I'm changing your thread title to make it more descriptive of the problem being asked. Too-general thread titles, such as "Projectile motion" are not allowed as it is impossible to differentiate one such thread from another by thread title.
