1. The problem statement, all variables and given/known data ok heres the question A speed boat travels at 6.0 m/s [E] for 90s and then accelerates uniformly at 2.0 m/s² [E] for 5.0s. Caculate the displacement of the speedboat 2. Relevant equations is this the formula i am suppose to use for this question? Delta D= V1*Delta T+1/2*A(Delta T)² note that the a in that formula is suppose to be vector acceleration. for the time do i just add up 90 seconds and 5 seconds?
