A few seconds after a plane took off it was hit by a missile launched from a distance on the
ground. The path of the plane is described by y= (0.0005 x²) m. The missile traveled along
a parabolic path described by y = (160 x), where the coordinates are measured in meters.
If the components of the missile velocity in the horizontal and vertical directions are
constant at v; =120 m/s and v, = 100 m/s, respectively, and the plane was rising with a
constant upward velocity v, = 12 m/s, determine the magnitudes of the velocity and
acceleration of the plane the moment it was hit by the missile.
