Problem: A person who is 1.3 m tall throws a ball with a speed of 19m/s at an angle of 17 degrees above horizontal. One part of the problem asks me to find the x and y components of the ball's velocity before it hits the ground. I have tried using the vy^2 = voy^2 + 2ah for the y-component: vy^2 = (5.56)^2 + (2)(10)(1.3) = 7.54 and my x-component is just (19)(cos(17))= 18.17 m/s, but it is saying this is not the right answer. What am I doing wrong?
