# – A spaceship is measured to be 167m long while at rest relative to the observer. If this spaceship now flies by the observer with a speed 0.

– A spaceship is measured to be 167m long while at rest relative to the observer. If this spaceship now flies by the observer with a speed 0.924 times the speed of light, what length does the observer measure? answer in units of m.- Energy is released during a nuclear reaction due to a conversion between mass and energy. Mass is not conserved. The initial and final amounts are different. If a total of 15g of mass were “missing”, how much energy is released? The speed of light is 3×10^8 m/s. answer in units of J. -find the speed relative to Earth of a uniformly moving spaceship whose clock runs 5s slow per hour compared with an Earth-based clock. Answer in units of c.
