Kinetic Energy and the Power of Human Climbing

Click For Summary
SUMMARY

This discussion focuses on calculating the height a person climbs and the average power exerted while climbing stairs. Given a mass of 68 kg, an individual step height of 0.16 m, and 12 steps in flight, the total height climbed is 1.92 m. Additionally, with a climbing time of 2.9 seconds, the average power exerted can be calculated using the formula Power = Work / Time, where Work is derived from gravitational potential energy.

PREREQUISITES
  • Understanding of gravitational potential energy calculations
  • Basic knowledge of power and work in physics
  • Familiarity with the formula for kinetic energy
  • Ability to perform unit conversions and calculations
NEXT STEPS
  • Learn how to calculate gravitational potential energy using the formula PE = mgh
  • Study the relationship between work and power in physics
  • Explore the concept of kinetic energy and its applications in real-world scenarios
  • Investigate the effects of different variables on climbing performance, such as mass and step height
USEFUL FOR

This discussion is beneficial for physics students, fitness trainers, and anyone interested in biomechanics or energy expenditure during physical activities like climbing stairs.

How to calculate the height of a person climbs from the third stair up? i don'[y know how to calculate it. HELP!

I have the mass=68kg, individual step height=0.16m, number of steps in flight=12

additional question: calculate the average power each person exerted while climbed the stairs.
i have the time= 2.9s for its average seconds.. Help!

Conservation of energy

In carrying out this investigation, what assumption do you make about each climber's kinetic energy?(the investigation being someone climbing a set of stairs, timing it and measuring the height) HELP!
