Determine the trajectory of a spherical cannonball in a stationary cartesian coordinate system that has a horizontal x-axis, a vertical y-axis, and an origin at the launch point. the initial velocity of the projectile in this coordinate system has magnitude v0 and makes an angle with respect to the x-axis of θ0 radians. the only forces acting on the projectile are gravity and the aerodynamic drag, d, which depends on the projectile’s speed relative to any wind that might be present. the equations describing the motion of th
