1.	For a man who wants to cross the river, with the shortest path `AB`, find the anglet `theta` (see figure) A. `sin^(-1)(3/4)`B. `sin^(-1)(4/3)`C. `30^(@)`D. Given situation is not possible
Answer» (d) For the man to cross the river frm the shortest path, `V_(m) sin theta=v_(r)` `sin theta=(v_(r))/(v_(m))` `sin theta=4/3` `theta =sin^(-1)(/3)` But it is not possible, because `sin theta` could not be greater than `t`. Hence the man could not cross the river from the shortest path `AB`.
