Question

Figure shows top view of an airplane blown off course by wind and magnitude of velocity of wind to be same in each case ${\overrightarrow{v}}_{A/w}=$ velocity of airplane relative to wind ${\overrightarrow{v}}_{w/g}=$ velocity of wind in ground frame. Then which is not correct?

• A. Airplane travels fastest across ground in case (d)
• B. Airplane travels slowest across ground in case (a)
• C. Airplane experiences maximum lateral displacement in case (a)
• D. In none of the cases velocity of wind with respect to air planes can be directed along south-west

Answer 1

Answer: (B)

Airplane travel slowest across ground in case ‘c’.
