(B) The initial vertical velocity of the body is $u_y = 0 \ m/s$. The height is $h = 1960 \ m$. Using the equation of motion $h = \frac{1}{2} gt^2$,we can find the time $t$ taken to reach the ground:$1960 = \frac{1}{2} \times 9.8 \times t^2$$t^2 = \frac{1960 \times 2}{9.8} = 400$$t = 20 \ s$Now,convert the horizontal velocity $v$ from $km/h$ to $m/s$:$v = 540 \times \frac{5}{18} = 150 \ m/s$The horizontal distance $AB$ covered by the body is given by $AB = v \times t$:$AB = 150 \times 20 = 3000 \ m$

An aeroplane is flying in a horizontal direction with a velocity of $540 \ km/h$ at a height of $1960 \ m$. When it is vertically above the point $A$ on the ground,a body is dropped from it. The body strikes the ground at point $B$. The distance $AB$ is equal to $(g = 9.8 \ m/s^2)$ (in $m$)
