A bug crawls 4 meters east across the kitchen floor in 20 seconds before someone steps on it and squishes it. What is its velocity?

Sagot :

Considering the definition of velocity, the velocity is 0.2 m/s due east.

Definition of velocity

Velocity is a physical magnitude that relates the displacement of an object, the time it takes to make this change in position and direction, so it is considered a vector magnitude.

In other words, the velocity can be defined as the amount of space traveled per unit of time with which a body moves, considering the direction, and can be calculated using the expression:

velocity= distance traveled÷ time

Velocity has units of distance/time and includes direction of travel.

This case

In this case, you know:

  • distance traveled= 4 meters
  • time= 20 seconds
  • direction= east

Replacing in the definition of velocity:

velocity= 4 meters÷ 20 seconds

Solving:

velocity= 0.2 m/s

Finally, the velocity is 0.2 m/s due east.
