Homework Statement
A person's mass is 28 kg. They climb the 4.8m ladder of a slide and reach a velocity of 3.2 m/s at the bottom of the slide. How much work was done by friction on the person?
Homework Equations
KE=1/2mv^2
PE=mgh
W=Fd
i think these are all the equations that apply
The Attempt at a Solution
i think you could find the potential energy=28(9.8)(4.8), which equals the kinetic energy,
then i don't know what to do but i know what i did is wrong
thank you for any help
