JAMB - Physics (1999 - No. 39)

The diagram above shows the velocity-time graph of a vehicle. Its acceleration and retardation respectively are
8.0 ms-2, 4,0 ms-2
4.0 ms-2, 8.0 ms-2
4.0 ms-2, 2.0 ms-2
2.0 ms-2, 4.0 ms-2

Açıklama

Acceleration = slope = AE/OE = 80/20 = 4m/s2
∴ acceleration and retardation = 4m/s2; 2m/s2
