Distance (km) 30 Velocity (km/h) 25 20 15 10 5 0 O 0 O 1 km/h O2 km/h O 3 km/h Suppose the given graph shows the velocity of a car in a 24- hour journey. Which among the following statements is INVALID? 20 15 10 1 2 3 4 5 6 7 8 9 10 11 12 13 14 1 Time (h) 5 10 Time (hour) The greatest velocity recorded is 15 km/h. 5 15 20 The acceleration for the first 3 hours is the same as the acceleration on the 13th to 18th hour of the trip. The magnitude of the car's acceleration at 0-3 h and 7-10h is equal. The car was at rest for three (3) v Which among the following d-t graphs correspond to the given v-t graph below? d III Hi O IV O III OI O II O -96 m/s^2 O-72 m/s^2 O-60 m/s^2 O-54 m/s^2 velocity (m/min) 80 60 40 20 V -20 - 40 An object's velocity, v, in meters per second is described by the following function of time, t, in seconds for a substantial length of time.
