Time left 1:26:3 A vehicle traveling between 2 stations that are 2 km apart starts from rest and accelerates over 3/5 of the total distance. After reaching the maximum speed, the driver steps on the brakes and the vehicle decelerates at a constant rate and comes to rest after 2 km and a total travel duration of 4 min. Analyze the motion of the vehide on a appropriate speed-time graph and then calculate: • The maximum speed observed during the journey m/s • The duration of acceleration tace 8 • The duration of deceleration Idee S • The acceleration : m/s2 and magnitude of the deceleration m/s2 You may need an speed-time graph for more accuracy on the following Change of speed during the 72 th second of motion: Av= m/s Distance covered during the 192 the second di motion: 172 The total distance covered after 192 s of motion Docht
