Question

for the acceleration time graph shown in figure the change in velocity of a particle from T is = 20 to 30 = 6 seconds

Answer 1

Acceleration is the vector quantity.

Velocity is defined as time rate of displacement, where as acceleration is defined as the time rate of change of velocity.

Motion is uniformly accelerated motion and it could be quite non-uniformly accelerated based on the velocity changes with time.

Change in velocity of a particle from T is = 20 to 30 = 6 seconds are known
