A passenger sits still on a train moving 30 m/s east relative to the ground. Which description is correct?
Which statement best describes a reference frame in kinematics?
Two observers moving at constant velocity relative to each other assign different velocities to the same skateboarder. What should a physics student conclude?
A train moves east at constant velocity. A passenger drops a ball straight down. Neglect air resistance. Which pair of observations is correct?
Why must a velocity statement include a reference frame, such as relative to the ground or relative to the train?
A train moves 25.0 m/s east relative to the ground. A passenger walks toward the front at 1.5 m/s relative to the train. Take east as positive. What is the passenger's velocity relative to the ground?
A subway train moves 22 m/s east relative to the ground. A rider walks toward the back at 2.0 m/s relative to the train. Take east as positive. What is the rider's velocity relative to the ground?
A moving walkway travels 1.2 m/s east relative to the terminal. A traveler walks 1.6 m/s west relative to the walkway. Take east as positive. What is the traveler's velocity relative to the terminal?
Car A moves 30 m/s east relative to the road, and Car B moves 18 m/s west relative to the road. Take east as positive. What is Car B's velocity relative to Car A?
A cyclist moves 8.0 m/s north relative to the ground. A jogger ahead moves 3.0 m/s north relative to the ground. Take north as positive. What is the jogger's velocity relative to the cyclist?
Two cars travel east on the same straight road. The faster car moves 30 m/s relative to the road, and the slower car moves 24 m/s relative to the road. How does the slower car appear to the faster driver?
