Answer:
(a)Velocity of wind = 35 j
(b)Velocity of jet relative to air = 425 i
(c)True velocity of jet = 425 i + 35 j
(d)True speed of jet = = 426.88 mi/h
Direction of jet is, ∅ = = 5.38°
Explanation:
We can represent east direction by i and north direction by j.
The jet has a relative speed of 425 mi/h relative to the air.
The wind is blowing due north with a speed of 35 mi/h = 35 j
425 mi/h is the relative speed with respect to wind that is
Velocity of jet wrt wind= =
425 i = - 35 j
= 425 i + 35 j
(a)Velocity of wind = 35 j
(b)Velocity of jet relative to air = 425 i
(c)True velocity of jet = 425 i + 35 j
(d)True speed of jet = = 426.88 mi/h
Direction of jet is,
∅ = = 5.38°
