Question:

how do you find work with a upward acceleration?

A crane lifts a 705 kg girder 8.40 m.How much work does the crane do lifting with upward acceleration 1.39 m/s^2?

Answer:

Haven't tried them 'cause I'm using my old reliable steel bikeThough its a little heavy but more reliable on bumps and jumps.
My suggestion is to locate better forks that have had the fee decreased because of fact of a stupid shade or some thingi offered Odyssey CS2 forks for $89.ninety 9 (?sixty 8.37) a whilst lower back in Matte Kelly green because of fact it became $40 (?30.39) offOn Danscomp you may get Odyssey Director forks in white for $ninety 9 (?seventy 9.ninety seven)Odyssey forks are lots of the right because of fact they have an incredible guarantee and could replace in the event that they are broken or bent.
I think the Odyssey Director Forks are the best forks that you can buyThere made of 41thermal material so you are always protected from the forks bending, cracking, snapping etcYou can't change the forks thought e.gwidening 10mm holes to fit a 14mm axle, otherwise you warranty will be void.
work done force distance First calculate work done against gravity : work mgh work 7059.88.4 work 58,035.6J Then calculate the work done in accelerating the girder force mass acceleration force 7051.39 force 979.95 980J Work force distance work 9808.4 work 8,232J Total work done 58,035.6J + 8,232J 66,267.6J Adjust for sig figs: work done 66,300J
