1. The problem statement, all variables and given/known data A car 4m long came up behind a semi-trailer 20m long travelling at a steady rate of 72km/h. The car driver then overtook the truck. If the car pulled out from behind the truck with the front of the car 10m behind the rear of the truck and accelerated at 3.5 m/s2 until the rear of the car was 10m in front of the truck, how far would the car travel and how long would it take? 2. Relevant equations v = u + at v2 = u2 + 2ar r = ut + 1/2 * at2 3. The attempt at a solution What I've gotten so far is this: The back of the car is 34m behind the front of the truck They are travelling, initially, at 20m/s Therefore, the distance from the initial to final position is 44m (if both were stationary) The acceleration of the car is 3.5 m/s2 Could someone kindly lead me in the right direction?
