A car is traveling along a straight road at a velocity of +30.0 m/s when its engine cuts out. For the next ten seconds the car slows down, and its average acceleration is a₁. For the nex five seconds the car slows down further, and its average acceleration is a2. The velocity of the car at the end of the fifteen-second period is +22.2 m/s. The ratio of the average acceleration values is a₁/₂ = 1.24. Find the velocity of the car at the end of the initial ten-second interval. m/s
