I'm not a student, but this seemed like the correct place to put a question.
I need to know how much power it takes to accelerate a motorcycle chain weighing 1 pound in 1 second to a speed that would equal 20mph at the wheel from a dead stop.
The wheel has a diameter of 20 inches.
The drive sprocket has a diameter of 2.25 inches.
The driven sprocket has a diameter of 8.5 inches.
If for some reason we need the length of the chain, I suppose that would be 100 links at 5/8 inch per link.
Assume all frictions are zero and all sprockets and wheels are massless.
Here's where I tried:
