Question

a car pulling a 1500-kg trailer produces an acceleration of 0.50m/s^2.
a)the frictional force in the wheels of the trailer is 125N. what force is the car exerting on the trailer?
b) what force is the trailer exerting on the car?

Answer 1

a) Fnet (on trailer) = M*a

= 1500*0.5 = 750 N
= Fcar - Fwheels
= Fcar - 125
Fcar = 875 N

b) -875 N (oppostite reaction)

Answer 2

1500*0.5=750
750+125=875

Answer 3

that's wrong ^^
