A soccer ball is kicked from ground level across a level soccer field with initial velocity vector v0 = 5 m/s at θ = 28° above horizontal. The soccer ball feels wind resistance which causes it to slow horizontally with constant acceleration magnitude an x = 0.66 m/s2, while leaving its vertical motion unchanged. Assume any other air resistance is negligible. Choose the positive direction of x from initial point towards final point of flight. Use a Cartesian coordinate system with the origin at the ball's initial position.
