3m east and 15m west evens out to 12m west. That's one side of a triangle. The second side is 2.5m north.
The third side is your displacement,
use Pythagorean's Theorem to determine this.
a^2+b^2=c^2, that works out to 12^2+2.5^2=c^2.....144+6.25=c^2
<span>150.25=c^2
and
finally
c=12.26,
or 12m</span>
a=v/t
a=38/10
a=-3.8 m/s^2
You put the negative in front of 3.8 because it decelerated.
Hope it helps and is correct :)
If the box is moving at constant velocity, net force must be zero, so:
F + fr = 0
fr = -F
<u>fr = -40 N</u>
