Question

I'm stuck on number 4... help please?

Answer 1

`V= (\Delta S)/(\Delta t) = (5)/(15) = (1)/(3) m/s`

Answer 2

Average speed = (distance covered) / (time to cover the distance) =

(5m) / (15 sec) =

(5/15) (m/s) = 1/3 m/s .

Average velocity =

(displacement) / (time spent traveling) in the direction of the displacement

Average velocity = (5m) / (15 sec) left =

(5/15) / (m/sec) left =

1/3 m/s left.

A number without a direction is a speed, not a velocity.
