The diagram above shows the velocity-time graph... - JAMB Physics 1999 Question
A
8.0 ms-2, 4,0 ms-2
B
4.0 ms-2, 8.0 ms-2
C
4.0 ms-2, 2.0 ms-2
D
2.0 ms-2, 4.0 ms-2
correct option: c
Acceleration = slope = AE/OE = 80/20 = 4m/s2
∴ acceleration and retardation = 4m/s2; 2m/s2
∴ acceleration and retardation = 4m/s2; 2m/s2
