Answer:
200 m/s
Explanation:
Given that,
A plane is moving due north, directly towards its destination. Its airspeed is 200 mph. A constant breeze is blowing from west to east at 60 mph.
We need to find the rate at which the plane is moving towards North. It can be given by :
[tex]V_x=v\cos\theta[/tex]
Where
[tex]\theta[/tex] is the angle with the North
[tex]V_x=200\times \cos(\dfrac{60}{200})\\\\=199.99\ m/s\\\\\approx 200\ m/s[/tex]
Hence, the plane is moving at a rate of 200 m/s.
