1. The problem statement, all variables and given/known data A speedboat starts from rest and accelerates at +2.01 m/s2 for 6.55 s. At the end of this time, the boat continues for an additional 6.45 s with an acceleration of +0.518 m/s2. Following this, the boat accelerates at -1.49 m/s2 for 8.80 s. Find the total displacement of the boat. 2. Relevant equations http://www.webassign.net/ebooks/cj6/pc/c02/read/main/c02x2_4.htm (Hopefully this is public access, if not, the equations can be determined from the work below, assuming that I am using the correct equations.) 3. The attempt at a solution v0=0 d1=0*6.55+.5*2.01*6.55^2=43.117 v1=2.01*6.55+.518*6.45=16.5066 d2=16.5066*6.45+.518*6.45^2=128.018 v2=16.5066+-1.49*8.8=3.3946 d3=3.3946*8.8+-1.49*8.8^2=-85.5131 Any help is, as always, greatly appreciated! Thank you in advance!
