Question

The diagram above shows the velocity-time graph of a vehicle. Its acceleration and retardation respectively are

Options

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


The correct answer is C.

Explanation:

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