Question

Acceleration-time graph of a body moving in a straight line is as shown in figure. The body started its motion from rest.

At which point is the body moving with the largest speed?

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

Answer: (B)

As we know that from acceleration-time graph Speed = Area under acceleration-time graph. From the graph, as given in the question
Area is maximum for point $0$ to point $2$
Therefore, the speed of the body is maximum (or largest) at point $2$
