A rainbow viewed from an airplane may form a complete circle. Where will the shadow of the airplane appear? Explain.
attashe74 [19]
The position of the sun must be at the horizon in order for the rainbow to appear.
The relative positions of the sun and plane make the rainbow appear as a full circle.
However, if the sun is at the horizon, the shadow of the plane will be behind the plane, not below it; this means that the shadow of the plane will not fall on the earth.

Two soccer players, Mia and Alice, are running as Alice passes the ball to Mia. Mia is running due north with a speed of 5.30 m/
never [62]

Answer:

A. 2.83 m/s

B. 39.55 degrees north of east

Explanation:

The velocity of the ball relative to the ground is the sum vectors of velocity of the ball relative to Mia and the velocity of Mia relative to the ground

If we take north east as positive direction then

Velocity vector of the ball relative to Mia is

=  =

Velocity of Mia relative to gorund is

<0, 5.3>

So velocity of the ball relative to the ground is

<1.8, -3.12> + <0, 5.3> = <1.8, 2.18>

Its magnitude is:

v = \sqrt{v_e^2 + v_n^2} = \sqrt{1.8^2 + 2.18^2} = \sqrt{3.24 + 4.7524} = \sqrt{7.9924} = 2.83  m/s

Its direction is

tan\alpha = \frac{v_e}{v_n} = \frac{1.8}{2.18} = 0.83

\alpha = tan^{-1}0.83 = 0.69 rad \approx 39.55 degrees  north of east
