Q1. A man makes three consecutive displacements :(1) from O to A, (2)from A to B and (3) back to O. The magnitude of OA is 29.70 meters and of AB 47.24 m. If theta= 38.2°, find out the magnitude of the third displacement. Reply in units of m.

Q2. A whale comes to the surface to breathe and then dives at an angle of 20 degree below the horizontal.
If the whale continues in a directly line for 196 m, how deep is it?

How far has it travelled horizontally?
