Homework Help: Physics(Please respond)

Posted by Hannah on Monday, May 28, 2012 at 8:07pm.

A golfer hits a shot to a green that is elevated 3.0 m above the point where the ball is struck. The ball leaves the club at a speed of 17.4 m/s at an angle of 35.0вк above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of the ball just before it lands.

I was going to do vx= 17.4 cos 35

vy=(17.4 sin 35) - 9.8(?)

and then do sqrt vx^2 + vy^2 but I wasnt sure if the vy equation was correct?
