Your car and the trailer it is towing are initially at rest. you apply an acceleration of 1.75 m/s2 to get the vehicles moving. the mass of your car is 1200 kg and the mass of the trailer is 540 kg. (a) determine the net force acting on the car.

The net force is defined as the vector sum of all the forces that are present in an object. The formula for net force is F=ma. Everything else cancels out like the force of gravity on the car, and the reactive force of the road surface, etc. It can be concluded that the force exerted by the trailer on the car is the same as that exerted by the car on the trailer. Given that the acceleration is 1.75 m/s^2, the car is 1200 kilograms, and the trailer is 540 kilograms. Thus, the net force acting on the car is equal to 21qkm/hr^2 

“foliation in geology refers to repetitive layering in metamorphic rocks. each layer can be as thin as a sheet of paper, or over a meter in thickness. the word comes from the latin folium, meaning "leaf", and refers to the sheet-like planar structure. “i found this on google i hope it you
