Question

If Rebecca is traveling at 7 m/s east for 1 hour how much is Rebecca displaced

Answer 1

25.2 km east

Step-by-step explanation:

The relationship between velocity and displacement is given by:

`v=(d)/(t)`

where

v is the velocity

d is the displacement

t is the time

In this problem, we have:

`v=7 m/s` east is Rebecca's velocity

`t=1 h=60 min=3600 s` is the time taken

Re-arranging the equation, we can find Rebecca's displacement:

`d=vt=(7 m/s)(3600 s)=25,200 m=25.2 km`

and the direction is same as velocity (east)
