A 1,280-kg car pulls a 350-kg trailer. The car exerts a horizontal force of 3,600-N against the ground in order to accelerate. What force does the car exert on the trailer? Assume an effective friction coefficient of 0.15 for the trailer.

Answer 1

acceleration=3600/(1280+350)

solve for acceleration
now, the trailer.
Net force=pulling-friction=mass*a

pulling force=350*a+350*g*mu

solve for pulling force.

Answer 3

What do you mean by mu?

Answer 4

mu is the friction coefficient. Upstairs anon is also wrong on how to solve it

Answer 5

This doesn’t help at all👌

Answer 6

Thxx, finally understand
