Solving for Normal Force in a 1k kg Car on a Dip

Click For Summary

Homework Help Overview

The problem involves a 1,000 kg car moving through a dip in the road, with specific parameters including the radius of the dip and the car's speed at the bottom. The focus is on determining the normal force acting on the car in this scenario.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the forces acting on the car, including normal force and weight, and how these relate to centripetal force. There are attempts to calculate acceleration and resultant forces, along with questions about the initial steps to take in solving the problem.

Discussion Status

The discussion is active, with participants exploring different aspects of the problem and questioning the relationships between forces. Some guidance has been offered regarding the forces involved, but there is no explicit consensus on the approach to take.

Contextual Notes

Participants are working within the constraints of a homework assignment, which may limit the information they can use or the methods they can apply. There is also a noted discrepancy between calculated values and expected answers, prompting further inquiry.

Homework Statement


a 1,000 kg car coasts into a slight dip in the road. The radius of the dip is 200-m. At the bottom of the dip the speed of the car is 10 m/s.
what is the magnitude and dirrection of the normal force?


Homework Equations


Sum of f=ma to find acceleration.


The Attempt at a Solution


the acceleration would be .5 m/s/s so wouldn't it just be .5*1000
the answer says it should be 10300 though.

there is the normal force acting as well as weight. The resultant of these two provide the centripetal force, mv2/r
 
so what steps do i take first?

Write down the resultant force in terms of the normal reaction and the weight
