A football is kicked at 25.0 m/s at an angle of 29.0° above the horizontal. Assume it starts 1.00 m above ground level. (Neglect any effects due to air resistance.) Describe the velocity vector of the ball in terms of its x- and y-components, vx and uy, respectively, when it is 4.50 m above ground level and still moving upward. Ux = 21.87 V = 7.7 m/s Incorrect Describe the velocity vector of the ball in terms of its magnitude v and angle 0 above the horizon when it is 4.50 m above ground level and still moving upward. Uy = m/s 12.12 0 = Incorrect 19.4 Incorrect m/s
