A special racing car starts from rest and accelerates in a straight line with a constant acceleration of 6.3 m/s². After 325 metres, it deploys a parachute which results in a deceleration of kv² where v is the speed of the car in m/s and k is a constant (has a unit of 1/m). If the car's speed slowed down to 42 km/hr 6.9 seconds after the parachute was deployed, determine the constant k and then give your answer to Z = 1000*|k| rounded to two decimal places. Note that |k| means the absolute value of k. Hints:
