What is the maximum acceleration of this car on a concrete surface?

Click For Summary

Homework Help Overview

The problem involves determining the maximum acceleration of a car on a concrete surface, given that two-thirds of its weight rests on the drive wheels. The subject area pertains to dynamics and frictional forces.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to calculate the force acting on the drive wheels based on the car's weight but seeks guidance on the next steps. Some participants suggest that the force is derived from friction and inquire about the coefficient of static friction. Others note the absence of this coefficient as a barrier to solving the problem.

Discussion Status

The discussion is ongoing, with participants exploring the implications of missing information, particularly the coefficient of friction. There is an acknowledgment that without this coefficient, the problem cannot be fully resolved.

Contextual Notes

Participants highlight that the problem does not provide the coefficient of friction, which is essential for calculating the maximum acceleration. This missing information is a point of contention in the discussion.

Two-thirds of the weight of a 1500 kg car rests on the drive wheels. What is the maximum acceleration of this car on a concrete surface?

(2/3) * 1500kg =1000kg
but I need the force so I can find the acceleration. What do I do next?

The force would be provided by friction. What's the coefficient of static friction between the tires and the concrete?
 
I don't know the coefficient of friction. The question and all the information given is:
Two-thirds of the weight of a 1500 kg car rests on the drive wheels. What is the maximum acceleration of this car on a concrete surface
 
Without the coefficient of friction (or a guess at it) you cannot solve the problem. Look to see if it's given in another part of your text.
