What Is the Gravitational Potential Energy of a Car on a 10-Degree Hill?

Click For Summary
SUMMARY

The gravitational potential energy (GPE) of a car with a mass of 1000 kg positioned at the top of a 10-degree hill is calculated using the formula GPE = Mgh. The height of the hill is determined to be approximately 8.816 meters, leading to a GPE of 86484.96 Joules. This calculation is confirmed as accurate by participants in the discussion. The use of trigonometric functions, specifically the tangent, is essential for determining the height from the base of the triangle formed by the hill.

PREREQUISITES
  • Understanding of gravitational potential energy formula (GPE = Mgh)
  • Basic knowledge of trigonometry, specifically tangent functions
  • Familiarity with units of measurement (kilograms, meters, Joules)
  • Concept of mass and weight in physics
NEXT STEPS
  • Study the application of trigonometric functions in physics problems
  • Explore the concept of energy conservation in mechanical systems
  • Learn about different forms of energy and their calculations
  • Investigate real-world applications of gravitational potential energy in engineering
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding the principles of gravitational potential energy and its calculations in real-world scenarios.

Car has a mass of 1000 kg its at a the top of a 10 degree hill. so if you were to draw a triangle the the base of the triangle would be 50 M in length as well.

a)what is it gravitational potential energy relative to the bottom of the hill?

Height = 50 * Tan 10
= 8.816

Potential energy =Mgh=1000 x 9.81 x 8.816 m=86484.96 J is this right?

looks ok! :smile:

(is something worrying you about it?)
