A dragster accelerates from rest for a distance of 450m at 14 m/s^2. A parachute is then used to slow it down to a stop if the parachute gives the dragster an acceleration of -7m/s^2 how far has the dragster traveled before stopping?
This question was asked and answered elsewhere. The answer is 450 + 900 = 1350 km, It takes twice as far to declerate as it does to accelerate, because the deceleration rate is half of the acceleration rate.
