Correct option is C
The time taken by the bomb to hit the ground is given byh=0×t+12gt2 or (2h/g)=t2∴ t=(2h/g)Horizontal speed of aeroplane = Horizontal speed of bomb (= v)The distance by which the bomb will miss the target is given by= horizontal velocity , time=vt=v(2h/g)Similar Questions
A body of mass 1 kg is moving along positive x-axis with velocity 2 m/s. At t = 0, a constant force, parallel to positive y-axis, starts acting on the body and after 5 sec, speed of the body is found to be 4 m/s. Then work done by the force in 5 sec is
