Question1
A space vehicle is travelling at 4190 km/h relative to Earth when the exhausted rocket motor is disengaged and sent backward with a speed of 88 km/h relative to the command module. The mass of the motor is four times the mass of the module. What is speed (in km/h) of the command module relative to Earth just after the separation?
Question2
A World War II bomber flies horizontally over level terrain with the speed of 275 m/s relative to the ground and at an altitude of 3.00 km. The bombardier releases one bomb.
(a) How far does bomb travel horizontally between its release and its impact on the ground? Ignore effects of air resistance.
(b) The pilot maintains plane's unique course, altitude, and speed through a storm of flak. Where is the plane while the bomb hits ground?
(c) The bomb hits target seen in the telescopic bombsight at the moment of the bomb's release. At what angle from the vertical was bombsight set?
