A spaceship leaves Earth traveling 0.668c. A second spaceshipleaves the first spaceship at a speed of 0.860c with respect to thefirst.
a) Calculate the speed of the second ship with respect to Earth ifit is fired in the same direction the first spaceship is alreadymoving. Express as fraction of c.
b) Calculate the speed of the second ship with respect to Earth ifit is fired directly backward toward Earth. Express as fraction ofc.
