A car 4m long came up behind a semi-trailer 20m long travelling at steady 72km/h (20m/s). After travelling behind the semi-trailer for some time, the driver of the car decided to overtake. If the care pulled out from behind the semi-trailer with the front of the car 10m behind the rear of the trailer and accelerated at 3.5m/s^2 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?
I does one solve this? I'm not sure whether I should add how the the truck is also travelling at 20m/s into the equation or not....
