You observe a rocket moving away from you. Compared to the passage of time measured by the watch on your wrist, is the passage of time on the rocket's clock will appear as running
O faster
• with the same speed as while on earth surface
• slower
O unpredictable as the speed
→
According to the formula E=mc²
O when two masses collide, we always get a lot of light
O energy can travel much faster than light (in fact its speed can be the speed of light squared)
a little bit of mass can be converted into a substantial amount of energy
mass has to travel at the speed of light before it can produce any energy
O Einstein was a male chauvinist twice over

• A) Find the value of y for the following
situation. An astronaut measures the length of
her spaceship to be 25.0 m, while an Earth-
bound observer measures it to be 100 m.
(b) What is unreasonable about this result?
(c) Which assumptions are unreasonable or
inconsistent?
• Solution (a) y = 0.250. (b)It is unreasonable
because the value of y is less than one. This opposed
the idea of length contraction. © It will give imaginary
value. The observer must measure the ship 25m, while
the astronaut measures her ship 100m.
