Calculate the centripetal acceleration of the car

Click For Summary
SUMMARY

The discussion centers on calculating centripetal acceleration and force for a car, with multiple attempts yielding varying results. The first attempt reported a centripetal acceleration of 7560 m/s², while subsequent attempts provided values of 25.032 m/s² and 2340 m/s², both with a consistent centripetal force of 4.7 Newtons. The inconsistency in acceleration values suggests a misunderstanding of the calculation process, prompting the need for clearer methodology and verification of the inputs used in the calculations.

PREREQUISITES
  • Understanding of centripetal acceleration formulas
  • Familiarity with Newton's laws of motion
  • Basic knowledge of physics units (meters, seconds, Newtons)
  • Ability to perform calculations involving force and acceleration
NEXT STEPS
  • Review the formula for centripetal acceleration: a = v²/r
  • Study the relationship between centripetal force and mass: F = m * a
  • Learn about the significance of consistent units in physics calculations
  • Explore common mistakes in physics problem-solving and how to avoid them
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in understanding the principles of centripetal motion and force calculations.

Homework Statement
Cloverleaf exits are approximately circular. A 1220 kg automobile is traveling 56 mph while taking a cloverleaf exit that has a radius of 35.9 m. Calculate the centripetal acceleration of the car and the centripetal force on the car. Remember that 1 mph = 0.447 m/s.
Relevant Equations
Centripetal acceleration = ________m/s2
Centripetal force = _______ Newtons
I tried this problem 3 times. I only have two attempts left.

First time: Centripetal acceleration: 7560 m/s^2
Centripetal Force: 4.7 Newtons
Second time: Centripetal acceleration: 25.032
Centripetal Force: 4.7
Third Time:
Centripetal acceleration:2340 m/s^2
Centripetal force: 4.7 Newtons

Not to be unkind, but are you using a random number generator? Please show more than that. Happy to help, but you have to help us.
 
What do you mean?
 
No I am not using a random number generator.
 
I figured this one out using a different forum. :)
