The acceleration of a particle is given by vec(a) = [2 hat(i) + 6t hat(j) + (2pi^(2))/(9) cos ((pi t)/(3)) hat(k)] ms^(-2). The initial conditions are vec(r ) (0) = x(0)hat(i) + y(0) hat(j) + z(0) hat(k) = vec(0), vec(v) (0) = (2 hat(i) + hat(j)) ms^(-1) wher vec(v) (0) = (d hat(i) (0))/(dt) = (dx (0))/(dt) hat(i) + (dy(0))/(dt) hat(j) + (dz(0))/(dt) hat(k) The position vector at t= 2 s is

1.	The acceleration of a particle is given by vec(a) = [2 hat(i) + 6t hat(j) + (2pi^(2))/(9) cos ((pi t)/(3)) hat(k)] ms^(-2). The initial conditions are vec(r ) (0) = x(0)hat(i) + y(0) hat(j) + z(0) hat(k) = vec(0), vec(v) (0) = (2 hat(i) + hat(j)) ms^(-1) wher vec(v) (0) = (d hat(i) (0))/(dt) = (dx (0))/(dt) hat(i) + (dy(0))/(dt) hat(j) + (dz(0))/(dt) hat(k) The position vector at t= 2 s is
Answer» `(3 HAT(i) + 8hat(j) + 10 hat(k))` `(8 hat(i) + 10 hat(j) + 3HAT(k))` `(10 hat(i) + 3hat(j) + 8hat(k))` `(3 hat(i) + 10 hat(j) + 8 hat(k))` ANSWER :B
