Projectile Motion: A bomber is flying horizontally at an altitude of 3200 feet with a speed of 400 feet per second when it releases a bomb. A projectile is launched 5 seconds later from a cannon at a site facing the bomber and 5000 feet from the point that was directly beneath the
bomber when the bomb was released, as shown in the figure.
