Question

The graph below shows the velocity of a car as it attempts to set a speed record. At what point is the car the fastest?

A. t = 4.1 s
B. t = 3.4 s
C. t = 2.1 s
D. t = 0.5 s

Answer 1

Answer:

B). 3.4 s

Explanation:

As we can see the graph is given between velocity and time

so here we can see that the velocity is changing here with time and initially for some time it moves with constant speed

Then it's speed decreases to next few second and then speed increases to its maximum value

The time after which velocity comes to its maximum value will reach after t = 3 s

so out of the all given options most correct option will be

$t = 3.4 s$

Answer 2

b is the correct answer i got it right for A P E X
