a) Suppose you decide to travel to a star 66 light-years away at a speed that tells you the distance is only 24 light-years. How many years would it take you to make the trip? Express your answer using two significant figures.
b)In its own reference frame, a box has the shape of a cube 1.5 mm on a side. This box is loaded onto the flat floor of a spaceship and the spaceship then flies past us with a horizontal speed of 0.90 cc.What is the volume (m3 ) of the box as we observe it?
A starship voyages to a distant planet 10 ly away. The explorers stay 1 yr, return at the same speed, and arrive back on earth 26 yr after they left. Assume that the time needed to accelerate and decelerate is negligible.a. What is the speed of the starship?b. How much time has elapsed on the astronauts’ chronometers?
A spaceship is traveling with constant velocity +0.4câ relative to Earth. At t = () a missile is fired from the spaceship in +
direction with speed 0.8c relative to the spaceship.
(You can assume that the missile reaches this velocity at the moment it is fired, and that the velocity of the spaceship doesn't
change when firing the missile).
a. What is the velocity of the missile relative to Earth? Give answer in units of c.
1.76 X
At time t₁ = 1 s (in the reference frame of the spaceship), the spaceship emits a laser pulse (i.e. a light pulse), towards the
missile. The laser pulse hits the missile and destroys it immediately at the moment of the hit.
The clocks in Earth, the spaceship and the missile were set to t = t' = t" = 0) at the moment at which the missile was fired.
b. Find the time (in seconds) of the destruction of the missile, in the frame of reference of the missile.
