An alien spaceship traveling at 0610c toward the earth, Ask an Expert

Academics

An alien spaceship traveling at 0.610c toward the Earth launches a landing craft. The landing craft travels in the same direction with a speed of 0.700c relative to the mother ship. As measured on the Earth, the spaceship is 0.250 ly from the Earth when the landing craft is launched.

(a) What speed do the Earth-based observers measure for the approaching landing craft?

(b) What is the distance to the Earth at the moment of the landing craft's launch as measured by the aliens?

(d) What travel time is required for the landing craft to reach the Earth as measured by Earth-based observers?

(e) What travel time is required for the landing craft to reach the Earth as measured by those on the landing craft?
