I need help on my science homework
After you coast down a hill on your bike,
you eventually come to a complete stop
unless you keep pedaling. Relate this to
the reason why perpetual motion is
impossible.
I'm 13, I don't race and i only go on trials. Plus i hit the odd jump. My nan would help me buy a $1700.00 baja (I pay 1000.00 she pays 700.00) It's not the best bike but its better than nothing. I could also buy a used bike. A honda crf 125-150cc. but if I get a honda my nan can't help me...
