1. The problem statement, all variables and given/known data A car starts from rest at time t=0 and accelerates at -0.6t+4 meters/sec^2 for 0[tex]\leq[/tex]t[tex]\leq[/tex]12. How long does it talke for the car to go 100 meters? 3. The attempt at a solution Since it says the acceleration is -0.6t+4 I integrated it and ended up with v(t)=-0.3t^2 + 4t + C for the velocity but I don't know what to do after this. I tried to intergrate it agian so that I can find the distance equation and set that equal to 100 but there is an unkown constant C that I have to figure out first. HELP!!
