A 2268 kg car is pulling a(n) 628.236 kg trailer. Together the car and the trailer have an acceleration of 2.65 m/s.s forward. The acceleration of gravity is 9.8 m/s.s
Neglecting frictional forces acting on the trailer, find the magnitude of the force exerted on the car by the road.
Answer in units of N

m = mass

g = gravity

Just Solve...)

@Yahoo!  but what about the frictional force??

anonymous · Answer

Neglecting frictional forces

anonymous · Answer

Remember that there is a normal force on the car from the road whih is equal to the weight of the car so that it doesn't sink into the road surface - it would be 9.8 multiplied by the mass of the car.

@Yahoo! neglecting friction for trailer only..

anonymous · Answer

we Neglect Friction Since...Coefficient of Friction is not Given..)

@ebaxter01 @Yahoo!  Is this the right way to solve as i did...??

anonymous · Answer

I dont Think so....Since.....the Road Only exerts a Vertical..Force..

anonymous · Answer

@Yahoo! I think road is also giving reaction to the tires in horizontal direction...

"find the magnitude of the force exerted on the car by the road."
