A spaceship moves away from Earth at a speed 0.417 c and fires a shuttle craft that then moves in a forward direction at 0.701 c relative to the ship. The pilot of the shuttle launches a probe forward at a speed 0.67 c relative to the shuttle. Determine the speed of the shuttle and the speed of the pribe realitive to earth.
