A bomber is flying horizontally over level terrain at a speed
of 275 m/s relative to the ground and at an altitude of
3.00 km. (a) The bombardier releases one bomb. How far
does the bomb travel horizontally between its release and its
impact on the ground? Ignore the effects of air resistance.
(b) Firing from the people on the ground suddenly incapacitates
the bombardier before he can call, “Bombs away!”
Consequently, the pilot maintains the plane’s original
course, altitude, and speed through a storm of flak. Where
is the plane relative to the bomb’s point of impact when the
bomb hits the ground? (c) The plane has a telescopic bombsight
set so that the bomb hits the target seen in the sight at
the moment of release. At what angle from the vertical was
the bombsight set?

Step 2

Consider the horizontal displacement.
