the work calculation is the total work
the components are not separable
... not enough information
A 62kg cyclist changes the speed of a 12kg bicycle from 8.2m/s to 12.7m/s. Determine the work done.
I used change in energy = work to find work against inertia which was 3479.85
Then I used V^2=V.^2 + 2ad to get ad=47.025
I then used W=mad to get work against friction, my problem is that was also 3479.85...
What am I doing wrong?
Thank you! ☺

What I understood was that Wtotal=the sum of all work, but is what I did maybe Wtotal?
