2019-IIT JEE CLASS-IX-P1)-(eSANKALP1923WB,ESANKALP192JRDUM
Paragraph for Questions 12 to 14
A particle 'A' starts moving from point A with constant velocity 6 m/s along x - axis. Another particle 'B' initially
at rest starts moving along x - axis after (8/3) sec of 'A' from the same point, with an acceleration a=4 m/s.
Based on the above information, answer the following questions.

13.
In case, both had started simultaneously, find the distance travelled by the particle 8 when particle A
has already travelled 18 meters
(A) 12 m
(B) 15 m
(C) 18 m
(D) 20 m
14.
lo case, both had started simultaneously, find the velocity of particle B, when the particle A has covered
a displacement of 36 m
