If the velocity of a particle is v = At + Bt2, where A and B are constants, then the distance travelled by it between 1 s and 2 s is,

• 3A + 7B

B.

Velocity of the particles is given as,
v = At + Bt2, where a and B are constants.

Integrating both sides, we get

Therefore, distance travelled between 1 s and 2 s is,
