A) \[\frac{\left| \overset{\to }{\mathop{V}}\, \right|}{\left| \overset{\to }{\mathop{a}}\, \right|}\]
B) \[\frac{\left| 2\overset{\to }{\mathop{V}}\, \right|}{\left| \overset{\to }{\mathop{a}}\, \right|}\]
C) \[\frac{\left| 3\overset{\to }{\mathop{V}}\, \right|}{\left| \overset{\to }{\mathop{a}}\, \right|}\]
D) none of these
Correct Answer: A
Solution :
\[{{\overset{\bullet }{\mathop{\text{V}}}\,}_{\text{Wind/Man}}}={{\overset{\to }{\mathop{\text{V}}}\,}_{\text{W}}}-{{\overset{\to }{\mathop{\text{V}}}\,}_{\text{M}}}\]\[|{{\overset{\to }{\mathop{\text{V}}}\,}_{\text{M}}}|=|{{\overset{\to }{\mathop{\text{V}}}\,}_{\text{W}}}|\] \[\text{V}=0+\]at\[t=\frac{|\overset{\to }{\mathop{\text{V}}}\,|}{|\overset{\to }{\mathop{\text{a}}}\,|}\]You need to login to perform this action.
