Objects traveling at relativistic speeds will appear to a stationary observer as shorter, as- suming that it is parallel to the direction of its motion. Using the equation for Lorentz contraction, find the following, where c is the speed of light: a) A spaceship is traveling with a velocity 0.8c. If it is 200m long in its rest frame (when the object is not moving), how long do you observe it to be? Assume that you can see the entire...

Question I need answered is bold faced here:
Relativistic Mass Still standing in the same spaceship... With
respect to an observer in a given frame of reference, how fast
would the spaceship have to move in order for your [moving] mass to
be double your resting mass? From your perspective, what
will be your mass on board the spaceship? In the last two weeks we
have investigated time, length, and mass at very high velocities.

An object, with mass 93 kg and speed 23 m/s relative to an observer, explodes into two pieces, one 3 times as massive as the other; the explosion takes place in deep space. The less massive piece stops relative to the observer. How much kinetic energy is added to the system during the explosion, as measured in the observer's reference frame
