If a young girl is in a truck that is rolling down a hill with a force of 8765 N, what force must the brakes apply on the truck to have the truck roll at a constant speed? Would she have to apply more than 8765 N or less than 8765 N to get the truck to stop?

My thoughts are, she'd have to apply a force of 8765 N to get the truck to zero acceleration, right? And to get it to stop it'd have to be more than 8765 N??

That is exactly correct. Once she gets it to constant speed, she then has to apply another, additional force to get to decelerate to speed of 0.

Alright, thanks :)

just checking if I was on the right track.

You're welcome! It's great to hear that you were on the right track with your thoughts. Understanding the concepts of force and acceleration can be helpful in solving physics problems like this. If you have any more questions, feel free to ask!
