Answer:
1176 N
Step-by-step explanation:
We are given that
Mass of car=
1280 kg
Mass of trailer=
=350 kg
Car exerts a horizontal force against the ground =
N
Coefficient of friction=

We have to find the force exerted by car on the trailer.



Substitute the values then we get




Force exert on the trailer



Hence, the car exerts force on the trailer=1176 N
