(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A mass 0.40 kg is released and slides down the incline. The maximum velocity ( taken the instant before the mass reaches the bottom of the incline ) is 1.00 m/s. What is the kinetic energy at that time? What percentage of the potential energy of the system is not converted into kinetic energy due to friction? (converted into heat instead)

I dont quite understand how to find out the percent of potential energy lost..thanks for any help!

2. Relevant equations

I solved for the kinetic energy correctly by using

W=KE=1/2mv^2

3. The attempt at a solution

=1/2(.4)(1)^2

=.2 Joules

i'm not sure about how to solve for the percent of potential energy lost..thanks
