Question

IP Two rocket ships are racing toward Earth, as shown in the figure. Figure 1) Ship A is in the lead, approaching the Earth at 0.71c and separating from ship B with a relative speed of 0.45c. of 1 Figure 1 Ship A Ship B1) 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.
