# Work and kinetic energy problems with solutions

Physics 1120: Work & Energy Solutions Energy 1. In the diagram below, the spring has a force constant of 5000 N/m, the block has a mass of 6.20 kg, and the height h of the hill is 5.25 m. Determine the compression of the spring such that the block just makes it to the top of the hill. Mechanics: Work, Energy and Power Work, Energy and Power: Problem Set Problem 1: Renatta Gass is out with her friends. Misfortune occurs and Renatta and her friends find themselves getting a workout. They apply a cumulative force of 1080 N to push the car 218 m to the nearest fuel station. Determine the work done on the car. Audio Guided Solution

Work, Energy and Power: Problem Set Overview This set of 32 problems targets your ability to use equations related to work and power, to calculate the kinetic, potential and total mechanical energy, and to use the work-energy relationship in order to determine the final speed, stopping distance or final height of an object. Work example problems | Work and energy | Physics | Khan ... David goes through some example problems on the concept of work. Created by David SantoPietro. ... Work/energy problem with friction | Work and energy ... Kinetic Energy, ... Work, Energy and Power formula with problems and solutions Learn about concepts of work, energy and power with formulae. Practice problems with solutions to understand relationship between force, work, energy and power. Work is calculated as force times distance. Power is the rate at which work is being done. Kinetic Energy Examples (solutions, videos, activities) Kinetic Energy The following diagram shows the formula for kinetic energy. Scroll down the page for more examples and solutions on how to use the formula. In this lesson, we will • Describe what is meant by kinetic energy. • Calculate kinetic energy for a moving object. Kinetic energy is the energy stored in moving objects.

## Work and Energy Practice Problems KEY Note: Question 11 should read 68.6 N not 686 N. Question 12 should read: “…He pulls the box 12.0 m.”
