A particle initially at rest starts moving along x-axis.Its acceleration varies with time as a=6tm/s^(2) .If it starts from x=10m .Then the position of particle at t=2s is

A point initially at rest moves along x-axis. Its acceleration varies with time as a = (6t + 5) m//s^(2) . If it starts from origin, the distance covered in 2 s is:

A particle, initially at rest, starts moving in a straight line with an acceleration a=6t+4 m//s^(2) . The distance covered by it in 3 s is

A particle starts from rest and moves with acceleration a which varies with time t as a=kt where k is a costant. The displacement s of the particle at time t is

A particle 'A' starts moving frorri point A with constant velocity 4 m/s along x-axis. Another particle 'B' initially at rest starts moving along x-axis after (8/3), sec after the start of A, with acceleration varying a=4=(3-t) m//s^(2) Variation of velocity uf the particle B with time is best represented by :
