Answer 2

Answer:

The acceleration is maximum for the segment BC.

Step-by-step explanation:

• A velocity versus time graph shows how velocity varies over time.
• An object's displacement, acceleration, and velocity as well as the direction in which it is going, may all be understood using this sort of graph.
• The area under a velocity-time graph is equal to displacement, and the slope of the line in a velocity vs. time graph is equal to the acceleration.
• Slope is calculated by the ratio of the change in the y-axis to the change in the x-axis

     ∴ Slope = Change in y-axis/ Change in x-axis ⇒ Slope = Δy/Δx.

       When we add the values of the y-axis and x-axis, we get,

    ∴ Slope = Change in velocity/ Change in time  ⇒ Slope = Δv/Δt.

This is the same as the acceleration equation. Thus, acceleration is equal to the slope of a velocity vs. time graph.

• The acceleration is greater when the slope is steeper. Similar to this, the acceleration is lower when the slope is shorter or less steep.

• When the slope is negative, so is the acceleration. Similarly, acceleration is positive when the slope is positive.
• And if the slope is 0, there is no acceleration and the object is either stationary or traveling at a constant pace.
• Since, BC has the greater slope, the acceleration is maximum for BC.
