1. The problem statement, all variables and given/known data th rocket driven sled sonic wind no. 2 used for investigating the physiological effects of large accelerations, runs on a straight, level track 1070m long. Starting from rest. it can reach a speed of 224m/s in 0.900s compute for its acceleration assuming that it is constant 2. Relevant equations im confused which equations do i have to use is it Vf=V+at Vf2]=V2+2ax or x=Vt+1/2at2 my v=0, Vf=224m/s, t=.900s, x=1070 is this correct?
