An astronaut is doing repairs when he accidentally drops a tool. It floats away from him at a rate of 2.0 meters every 1.0 secon

AlexFokin [52]

Answer: Graph Y

Explanation:

The tool is floating at a rate of 2.0 meters every 1.0 seconds so both the distance and time are changing. Neither is constant which rules out graphs X and Z.

The distance is increasing as time increases which rules out Graph W which depicts a scenario where the tool is coming closer to the astronaut as time increases.

Correct option is therefore Graph Y as it shows the tool moving at a rate of 2.0 meters per second.
