Solution

Given,

An Acceleration time graph,

So, the area under the velocity time graph shows the change in velocity,

Let the time t0 the particle accuire the initial velocity,

Therefore the change in velocity of the particle in the time t is:

So, Area under the velocity time graph is zero.

Thus Area of AOB=areaofBCD

12OA×OB=12OC×CD

OB2tanθ=CD2tanθ

(OB)2=(CD)2

4=t04

t0=8
