Question

If an object moves 80 meters North along a straight path for 4 seconds, what is the average velocity?

Answer 1

Average velocity is defined as the ratio of displacement and time

where displacement is straight line distance between initial point and final point

here we know that object moves in straight line towards North by 80 m

time taken = 4 s

now using the formula

`velocity = (displacement)/(time)`

`v = (80)/(4)`

`v = 20 m/s`

So the velocity of this motion is 20 m/s towards North
