Question

a shopper walks westward 5.4 meters and then eastward 7.8 meters. for this motion, what is the distance moved? distance (m) = what is the magnitude and direction of the displacement? magnitude (m) = dirn =

Explanation:

Step1: Calculate the distance

Distance is the total path length.
$d = 5.4+7.8$

Step2: Calculate the displacement

Displacement is the net change in position. Let west be negative and east be positive.
$x=-5.4 + 7.8$

Answer:

Distance $(m)=13.2$
Magnitude $(m)=2.4$
Dir'n = East
