$(20$ pts$.)$ A $3,300kg$ truck is about to tow a $1,360kg$ car up a hill that makes an angle of $=18$ with respect to the horizontal. The rope attached from the ruck to the car makes an angle $=25$ with respect to the horizontal. The coefficient of static friction between the truck tires and the road is $0\mathrm{.}75.$ Ignore friction on the car's tires due to the road. Starting from rest they move with constant acceleration until, $550$ m up the hill.

Their speed is $13\frac{m}{s}.$

What is the total frictional force on the truck's tires? You may not need all the given information.

$T$ Trob $=3,300kg$

$C=1360kg$

$a=180$

$B=25$

Sratic Friction $=0\mathrm{.}75$ Constant vec$(a)=550m$

sped $=13\frac{m}{s}$

Draw FBD for both, the car and truck
