1. The problem statement, all variables and given/known data Starting from rest, a cyclist coasts down the starting ramp at a professional biking track. If the ramp has the minimum legal dimensions(1.5 m high and 12m lomg) find a) the acceleration of the cyclist ignoring friction b) the acceleration of the cyclist if all sources of friction yield an effective coefficient of friction = .11 c)time taken to reach the bottom of the ramp, if friction acts as in (b) 2. Relevant equations My concern is the part a. V1= 0 v2= ? a=? m=? d=12m I cant use Newton's 2nd law to find the a because the mass is not given nor the force. I looked at all kinematic equation and none of them works as well...so how do i approach solving this problem?
