Velocity of a particle moving in a straight line varies with its displacement as `v = sqrt(4+4x)m//s` where x is displacement. Displacement of particle at time t = 0 is x = 0. Find displacement (in m) of particle in 2 sec. |

Answer» Correct Answer - 8 `underset(0)overset(x)int(dx)/(2sqrt(1+x))=underset(0)overset(2)intdt` `(sqrt(1+x))_(0)^(x)=(2)` `sqrt(1+x)-1=2` `1+x=9` x = 8 |
