Particle A starts from rest and moves along a straight line. Acceleration of the particle varies with time as shown in the graph. In 10 s the velocity of the particle becomes `60 m//s` and the acceleration drops to zero. Another particle B starts from the same location at time `t = 1.1 s` and has acceleration – time relationship identical to A with a delay of `1.1 s`. Find distance between the particles at time `t = 15 s`.

Answer

`66m`
