Aspaceship travels at a speed of 0.95c to the nearest star, alpha centauri, 4.3 light years (ly) away. how long does the trip take from the point of view of the passengers on the ship?

Taylor's experiment: 1. accurately measured the speed of light 2. locked together the phases of two light sources so that the interference pattern would not shift 3. showed that man's reaction time was much slower than the speed of light 4. showed that individual photons have wave characteristics

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?
