A drag car starts from rest and moves down the racetrack with an acceleration defined by a = 50 - 10r, where a and fare in m/s^2 and seconds, respectively. After reaching a speed of 125 m/s, a parachute is deployed to help slow down the dragster. Knowing that this deceleration is defined by the relationship a = - 0.022v^2, where v is the velocity in m/s, determine the total time from the beginning of the race until the car slows back down to 10 m/s and the total distance the car travels during this time. The total time from the beginning of the race until the car slows back down to 10 m/s is s. (Round the final answer to one decimal place.) The total distance the car travels during this time is m. (Round the final answer to one decimal place.)
