Kinetic Energy in Joules of an Object

Click For Summary
SUMMARY

The kinetic energy of a car traveling at 60 miles per hour with a mass of 800 kg is calculated using the formula KE = 1/2 m * v². The correct conversion of 60 miles per hour to meters per second is approximately 26.82 m/s. Substituting these values into the equation yields a kinetic energy of 287,724 Joules. This calculation confirms the accuracy of the solution provided by the user seeking assistance.

PREREQUISITES
  • Understanding of the kinetic energy formula (KE = 1/2 m * v²)
  • Ability to convert units from miles per hour to meters per second
  • Basic knowledge of mass and its measurement in kilograms
  • Familiarity with the concept of energy measured in Joules
NEXT STEPS
  • Learn unit conversion techniques, specifically between miles per hour and meters per second
  • Study the principles of kinetic energy and its applications in physics
  • Explore additional physics equations related to motion and energy
  • Practice solving problems involving kinetic energy with varying masses and velocities
USEFUL FOR

Students in physics courses, particularly those with a focus on mechanics, as well as individuals seeking to understand the principles of kinetic energy and its calculations.

Homework Statement


A car is traveling at a constant 60 miles per hour. What is its kinetic energy in Joules if its mass is 800 kg?


Homework Equations


KE = 1/2m * v2 (?)


The Attempt at a Solution


½(800kg)*(26.82 m/s)2 = 287,724 kg * m2/s2 = 287,724 J

I hope that looks right. I'm a business major and my advisor suggested this Physics class as "easy" for business majors. So far its not going so well. LOL Any help someone can offer on my solution would be great. Thanks.
