# Physics

On vacation, your 1200- car pulls a 540- trailer away from a stoplight with an acceleration of 1.50. What is the net force exerted by the car on the trailer?

1. You need dimensions with your numbers.

F = M a

will solve your problem. You have to assume that there is a negligible friction force where the trailer tires meet the road.

The car's mass does not matter. The trailer's mass does matter.
