Constants A rescue plane wants to drop supplies to isolated mountain climbers on a rocky ridge 235 m below. The horizontal velocity of the plane is 250 km/h (69.4 m/s). Rescue plane releases the supplies a horizontal distance of 425 m in advance of the mountain climbers Thrown upward? 235 m Thrown downward? Part A What vertical velocity (up or down) should the supplies be given so that they arrive precisely at the climbers' position (see the figure)? Express your...
1) As seen from Earth, what is
the speed, v, of ship B?
Express your answer using two significant
figures.
2) If ship A increases its speed by
0.10c relative to the Earth, does the relative speed
between ship A and ship B increase by 0.10c, by more than
0.10c, or by less than 0.10c? Explain.
3) Find the relative speed between ships A and B for the
situation described in part B.

A 735-kg two-stage rocket is
traveling at a speed of 6.80×103 m/s away from Earth when a
predesigned explosion separates the rocket into two sections of
equal mass that then move with a speed of 2.60×103 m/s relative to
each other along the original line of motion.
