A horizontal smooth square platform $ABCD$ is moving towards the right with a uniform speed $v$ . At what angle $θ$ must a particle slide from $A$ , on the platform, with speed $u$ so that it strikes the point $B$ ? (Assume $u$ to be uniform and $u > v$ )

Options:

Answer:

Solution:

$\Rightarrow u cos θ t = v t$

$\Rightarrow u cos θ = v$

$cos θ = \frac{v}{u}$

$θ = {cos}^{-1} (\frac{v}{u})$
