greetings all here is my question: Starting from rest, a cyclist coasts down the starting ramp at a professional biking track. if the ramp has the minimum legal dimensions (1.5m high and 12m long), find the acceleration of the cyclist, ignoring friction. i am having a hard time figuring this out. i use the pathagorus theorum to get the length of my track, 12.1m (also the hypoteneuse) but after that i am lost. the only force i know is gravity. am i missing something here?
