11: A- ballistic missile with a warhead takes off vertically and while accelerating gradually tilts the direction of flight . When it reaches the velocity 4.00 km/ sec in the direction 50 degrees above the horizontal, the warhead is disconnected from the missile body and continues to fly as a free-falling object over a long parabolic trajectory . How high does the the warhead go (above the altitude at which it was disconnected ) ? Km. How far from disconnect point in the horizontal direction is the warhead when it descends back to the initial altitude ? Kim How long does it take to cross this distance? sec # min . Neglect the earth curvature here
