The position vector of a moving particle at .t. sec is given by vec(r) = 3hat(i) + 4t^(2)hat(j) - t^(3)hat(k). Its displacement during an interval of t = 1s to 3sec is

The position vector of a moving particle at .t. sec is given by vec(r)

1.	The position vector of a moving particle at .t. sec is given by vec(r) = 3hat(i) + 4t^(2)hat(j) - t^(3)hat(k). Its displacement during an interval of t = 1s to 3sec is
Answer» `hat(j) - hat(k)` `3overset(.)i + 4overset(.)j - OVERSET(.)k` `9hat(i) + 36hat(j) - 27 hat(k)` `32hat(j) - 26hat(k)` ANSWER :D
