Answer:
the answer is given to be 36.6 mile/hour.
Explanation:
the speed is 100mile/h with respect to air.
Give v1 a chance to be the speed of the helicopter
What's more, v2 be the speed of the breeze which has greatness b
v1 = 100 cos 60o i + 100 sin 60o j
= 50i + 50√3j
What's more, from the other idea
v2 = an i
the resultant is given by
v1 = v1+v2
=(50+a)i + 50√3j
As given in the inquiry , the helicopter lands 45* east of north because of the breeze, at that point x part will be equivalent to y segment
50+a = 50√3
a = 50(√3-1)
a = 36.6 miles/hr
