Question

A mosquito is moving with a velocity $V\, = \,(0.5\,{t^2}\hat i\, + \,3\,t\hat j\, + \,9\hat k)\,m/s$ and accelerating in uniform conditions. What will be the directions of mosquito after 2s?

Accepted Answer

${\rm{ta}}{{\rm{n}}^{{\rm{ - 1}}}}\left( {\frac{{\sqrt {40} }}{9}} \right){\rm{from}}{\mkern 1mu} {\mkern 1mu} x - {\rm{axis}}$

Answer

${\rm{ta}}{{\rm{n}}^{{\rm{ - 1}}}}\left( {\frac{{\sqrt {85} }}{6}} \right){\mkern 1mu} {\rm{from}}{\mkern 1mu} {\mkern 1mu} x - {\rm{axis}}$

Answer

${\rm{ta}}{{\rm{n}}^{{\rm{ - 1}}}}\left( {\frac{{\sqrt {40} }}{9}} \right){\rm{from}}{\mkern 1mu} {\mkern 1mu} y - {\rm{axis}}$

Answer

${\rm{ta}}{{\rm{n}}^{{\rm{ - 1}}}}\left( {\frac{{\sqrt {85} }}{6}} \right){\mkern 1mu} {\rm{from}}{\mkern 1mu} {\mkern 1mu} y - {\rm{axis}}$
