You encounter a moving walkway that is 75 mm long and has a speed of 1.9 m/sm/s relative to the ground.How long would it take you to cover the 75 mm length of the walkway if, once you get on the walkway, you turn around and start walking in the opposite direction with a speed of 1.4m/s relative to the walkway?
A beam of light is moving directly along the spaceship, but through an old-fashioned fiber optic cable. The speed of light in the cable is 0.6 times the speed of light in a vacuum. The spaceship is moving at 0.8 times the speed of light. What speed do you observe from the ground?
Two children, one at the front of a parade float and one at the back, are playing catch with a ball. Each sees the other as tossing the ball at 4.0 m/s. The float moves down the road at 2.0 m/s. At what speed do the two children toss the ball from the point of view of a spectator watching the float move by?
Suppose that construction crews have set up a pair of blinking lights 60 m apart to mark a construction zone along a road. A car moves along the road with a speed of 30m/s toward the lights. Let us take the road to be the Home Frame and the car to be the Other Frame. In the Home Frame, the light farther from the car (light 2) blinks 0.66 s before the other light (light 1) blinks as the car approaches. (a) What is the time interval (t'2 - t'1) between the blink events in the car's frame? (Hint: Think about the sign). (b) What is the x displacement x'2 - x'1 between the events in the car frame?

A boat is docked on the southern shore of a swiftly moving river that is 262.0 m wide. The river flows from east to west with a speed of 4.00 m/s relative to the shore. There is a dock located upstream on the northern side of the river at an angle of 57.0∘57.0∘ relative to the shore (i.e. north of east). The boat is able to travel at a speed of 6.50 m/s relative to the water. If the boat travels directly to the dock on the northern shore at a constant speed, how long does it take to get there?

TRUE OR FALSE. An object seen by the human eye remains chemically mapped on the eye's retina for a brief time after viewing. This phenomenon is called phi. TRUE OR FALSE. The human mind needs to conceptually complete a perceived action. This phenomenon is called phi. TRUE OR FALSE. Anything less than 12fps will be smooth motion as the eye is able to detect the changes from one frame to the next.
