You will be surprised by this car's speed!!!!

A car moves with constant velocity \(2 m.s^{-1}\) for 5 second. After 5 second, the car accelerates as much as \(10 m.s^{-2}\). After a while, the car then start slowing with negative acceleration as much as \(10 m.s^{-2}\) until it stop. If the car moves for 15 second, find out the total distances of the car's move (in \(m\))!
