Question

the velocity-time graph of a vehicle is given below. answer the following questions on the basis of the following graph.​

Answer 1

Step-by-step explanation:

i) A; 20 m/s

B: 40 m/s

C: 0 m/s

ii) 40 s - 20 s = 20 s, meaning the vehicle traveled at the uniform velocity of 40m/s for 20 sec (which is where the graph is flat)

iii) a = Δv / Δt = (0-40) / (60 - 40) = -40/20 = -2 m/s²

The acceleration, in this case negative (slowing down), is the slope of the line from C to D.
