1. The problem statement, all variables and given/known data As a traffic light turns green, a waiting car starts with a constant acceleration of 6.0 m/s^2. At the instant the car begins to accelerate, a truck with a constant velocity of 21 m/s passes in the next lane. a) How far will the car travel before it overtakes the truck? b) How fast will the car be traveling when it overtakes the truck? 2. Relevant equations a=Vf-Vi/DeltaT deltad=1/2(Vi+Vf)deltat deltad=Vi x deltat + 1/2a(deltat)^2 deltad=Vf x deltat - 1/2a(deltat)^2 Vf^2=Vi^2+2a deltad 3. The attempt at a solution car Vi = 0 m/s a = 6.0 m/s^2 Delta d = ? truck Vi = 21 m/s Vf = 21 m/s a = 0 m/s^2 I can only see these variables in the question, and I don't know what formula to use. Could someone point me in a direction please? I'm really stressing over this, i've tried multiple times.
