Question

A crow flies 100 meters east in 250 seconds. What is the crow’s velocity in m/s?

Answer 1

Answer:

ok

thank you

Explanation:

velocity =

(distance between the start and end points) / (time to cover it) and the direction from the start point to the end point.

For this particular crow:

distance between start-point and endpoint = 100 meters time to cover the distance = 5 minutes

Velocity = (100 meters east) / (5 minutes) = 20 meters/minute East.

Converting to more familiar units:

(20 meter/minute) (1 minute / 60 seconds) = 1/3 meter/second East

OR

(20 meters/minute). (60 minute/hour) (1 mile / 1,609 meters)

= (20 - 60 / 1,609) (meter minute mile / = minute - hour meter)

= 0.746 mile per hour East.

Our poor crow has a problem. How he remains airborne is a mystery. This could be that very bird who Dr. Seuss named "Slow Joe Crow" !
