An autonomous delivery vehicle on a test track detects an obstruction on its path at time t=0t = 0t=0 seconds. The velocity-time graph below shows how the vehicle's velocity, v v\,v in metres per second (m s−1\text{m s}^{-1}m s−1), changes as it stops.
Which of the following statements is correct?
The vehicle travels a distance of 36.0 m36.0\text{ m}36.0 m while braking.
The vehicle has a reaction/latency time of 3.8 s3.8\text{ s}3.8 s.
The magnitude of deceleration during the braking phase is 6.3 m s−26.3\text{ m s}^{-2}6.3 m s−2.
The total distance travelled by the vehicle from t=0 st = 0\text{ s}t=0 s until it stops is 45.6 m45.6\text{ m}45.6 m.
