With bumpers touching, a 3,773 kg truck is pushing a 1,103 kg car. The truck and the car move forward together with a maximum forward force of 18,470 N. Assuming friction is zero, what is the magnitude of the force (in N) of the car's bumper on the truck's bumper? Hullo, everyone! I actually know the answer to this question, because I keep getting it marked as wrong - the answer is supposed to be 4178, but for the life of me, I can't figure out how. I thought it would be as simple as finding the acceleration, then multiplying by mass, but I've tried converting kg to g, tried the law of equal and oppositie reaction, tried the car's mass, tried the truck's mass, but I never even get close to the answer I've been given. The AI function on Bartleby, which I have often found quite useful, also can't get 4178. If anyone could send me the specific steps involved in getting this answer, I would be so grateful - thank you so much! 've tried everything with this question.
