A light body is projected with a velocity `(10hat(i)+20 hat(j)+20 hat(k)) ms^(-1)`. Wind blows along X-axis with an acceleration

A light body is projected with a velocity `(10hat(i)+20 hat(j)+20 hat(k)) ms^(-1)`. Wind blows along X-axis with an acceleration of `2.5 ms^(2)`. If Y-axis is vertical then the speed of particle after 2 second will be `(g=10 ms^(2))`
A. `25 ms^(-1)`
B. `10sqrt(5) ms^(-1)`
C. `30 ms^(-1)`
D. none of these
