2 The driver of a car accelerating uniformly from rest sees an obstruction. She brakes immediately bringing the car to rest with constant deceleration at a distance of 6 m from its starting point. The car travels in a straight line and is in motion for 3 seconds.

1. Sketch the \(( t , v )\) graph for the car's motion.
2. Calculate the maximum speed of the car during its motion.
3. Hence, given that the acceleration of the car is \(2.4 \mathrm {~m} \mathrm {~s} ^ { - 2 }\), calculate its deceleration.
