[SOLVED] Free Body Diagram, Newton's 3rd
SOLVED
A 1200 kg car pushes a 2000 kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push against the ground with a force of 4700 N.
(a) What is the magnitude of the force of the car on the truck?
(b) What is the magnitude of the force of the truck on the car?
fs=[tex]\mu[/tex]sn
F=ma
Fnetc/mc=FnetT/FT
I drew this free body diagram, I am not really sure how to set this problem up but I thought this would be a good start.
Wanted to see how "right" it is.
nc = normal force of car
nT = normal force of truck
fsc = static friction force
Fc on T = force of car on Truck
FT on c = force of Truck on car
mcg = weight of car
mTg = weight of truck

I've done a little dabbling with formulas from there but nothing great. I haven't solved anything so.. maybe I can at least figure out if my drawing is right.
