2D Kinematics, airplanes crashing wtf?? An airplane is flying with a velocity of 240 m/s at an angle of 30.0° with the horizontal, as the drawing shows. When the altitude of the plane is 2.4 km, a flare is released from the plane. The flare hits the target on the ground. What is the angle theta? There was a diagram with this, but it's pretty self explanatory. Vxo = 240(cos(30)) = 207.8 m/s Vyo = 240(sin(30)) = 120 m/s Vf^2 - Vi^2 = 2a (change in X) Vy^2 - 120^2 = 2(9.8)(2400) Vy^2 = 247.87 m/s (wrong!!) and theta: the inverse tangent of (247.87/207.8) =50.01 degrees Also wrong. I have no idea where I could have gone wrong. I thought I had this one!
