A rocket moves horizontally with a constant velocity ‘u’ at a height ‘L’. A guided missile is fired vertically with a speed ‘v’ when the rocket passes above it. Assuming that the missile always aims at the rocket with the constant speed ‘v’, find the time after which the missile strikes the rocket.

Hello Student,

We’ll do this by concept of relativity.
rel_dis=L
rel_vel=v
=>t=L/v
