The wind velocity can be calculated by vector subtraction of the plane's velocity relative to the ground (the observed travel path) and the plane's velocity relative to still air. This involves converting the velocities to their component forms along the east-west and north-south axes, performing the subtraction, and then converting back to a magnitude and direction.
This problem can be solved through the use of vector addition and subtraction. Let's denote the velocity of the plane as Vp, the velocity of the wind as Vw, and the resultant velocity (or the actual observed travel path) as Vr. These velocities are vectors, which mean they have both magnitude and direction.
Given that the plane had an airspeed of 185 km/h due south, which can be represented as Vp=185 km/h south. However, the actual path covered was Vr=135 km/h, 75° south of east. We can find Vw through the equation Vr = Vp + Vw, rearranged as Vw = Vr - Vp.
Following this calculation, we then need to convert these vector magnitudes and directions into components along the north-south and east-west axes. We then subtract corresponding components to find the wind velocity in terms of its north-south and east-west components, before finally converting these back into a magnitude and direction using Pythagoras' theorem and trigonometric functions.

How long is the ball in the air?
Round the answer to two significant digits
Answer:
The correct answer is t = 0.92s
Explanation:
Initial velocity v0 = 3.0 m/s
Displacement Δy = ?
Acceleration a = -9.8m/s2
Final velocity v = -6.0m/s
Time t=? Target unknown
We can use the kinematic formula missing Δy to solve for the target unknown t:
V=v0+at
We can rearrange the equation to solve to t:
V-v0=at
t= v-v0/a
Substituting the known value into the kinematic formula gives:
t= (-6.0m/s)-(3.0m/s)
————————————
-9.8m/s2
= -9m/s
—————-
-9.8m/s2
=0.92s
Sarah throws a ball directly upward at the edge of a cliff with a starting velocity of 3.0 m/s. It lands on the ground with a final speed of 6.0 m/s.
How long is the ball in the air?
Answer: 0.92
Answer:
car. The car starts from rest at sea level and has a speed of 29.0 m/s at an altitude of 2.20x10^2 m above sea level. Obtain the work done on the car by the combined forces of friction and air resistance, both of which are nonconservative forces.
