During which time period was the acceleration of the car the greatest?

a.) 5-8 seconds

b.) 0-2 seconds

c.) 2-3 seconds

d.) 3-5 seconds

c.) 2-3 seconds

Explanation:

Acceleration is defined as the ratio of change in velocity per unit time:

In a velocity-time graph, like the one attached here, acceleration corresponds to the slope of the curve.

Let's calculate the acceleration of the car in the different sectors:

a) 5-8 seconds:

b) 0-2 seconds:

c) 2-3 seconds:

d) 3-5 seconds:

So, the acceleration is greatest in c) 2-3 seconds (the negative sign means it is a deceleration)
