An observer (O) is standing on a long tunnel that has a rest length of 12 c.µs.  O sees a long train that he measures to be 12c.µstravel through the tunnel at a speed of 0.600c. The front and back of the tunnel are mounted with strobe lights so that when the front or end of the train reaches the end of the tunnel the light flashes.  So we have 4 events (flashes). Event 1:  Front of train enters tunnel. Event 2:  Front of...

A truck traveling at a constant speed of 28 m/s passes a more slowly moving car. The instant the truck passes the car, the car begins to accelerate at a constant rate of 1.2 m/s^2 and passes the truck 545 m farther down the road. What was the speed of the car (in meters/second) when it was first passed by the truck?
