1. I need help with this Alevel Physics projectile question!
A golfer strikes a golf ball and gives it a velocity of 42.0m/s at an angle of 36.9 degrees to the horizontal.
a) neglecting th air resistance, and considering the verticle component of velocity, calculate the maximum height reached by the ball.

Would you use the formula; v² = u² + 2as?
I had my s = 1.3m?

0 = 25.22 + 2*-9.8s
-25.22 = -19.6s
s = 1.3..

You did not square u

Square u. And you should get the answer in my spoiler.
