Parachute opens-a drag racer-starting from rest

Reference no: EM13538743

A drag racer, starting from rest, speeds up for 402 m with an acceleration of +21.0 m/s2. A parachute then opens, slowing the car down with an acceleration of -5.75 m/s2. How fast is the racer moving 2.90 102 m after the parachute opens?
