Question


The Coriolis Effect is an example of a "fictitious" force, causing the deflection (from straight line motion) of a moving object in a rotating reference frame In the northern hemisphere, for example, objects moving through the air are deflected to the right by the Coriolis Force" Consider a golfer here in Oregon. at exactly 45.0 degree latitude, hitting a golf bail's initial velocity is 48.0 degree above the horizontal. The golf ball is initially headed straight toward the hole for a hole-in-one, and would be a hole-in-one, except, The Earth is rotating!

Explanation / Answer

Air resistance will be there while playing golf and omitting it is rediculuos.
Since the hooks and slices which are the effects of the spin of the ball making small variations in wind resistance and large variations in the horizontal trajectory.

In the same way the ball is hit at perhaps 10 degrees from the horizontal but the lift from the spin keeps it in the air until the ball slows down. We can say that the ball stays in the air longer than these figures suggest.

Of course if you did the golf on the moon then we could ignore wind resistance. But the moon is not spinning as fast as the earth and the gravity is less so the effects would be different.

If you ignore reality and physics then you could calculate the following.
Vertical component = V sin(48)
Horizontal component = V cos(48)
t = 2 V sin(48) / g
and
So we know that, 2 V2 cos(48) * sin*48 / g = 275

V=52.05 m/s
Vcos(48) * t = 275

t=7.89 s
If you find the rotational speed of the earth at 45 degrees of latitude and use interpolation to find the speed 275 m south of this you have the DIFFERENCE in the two speeds.
(V = 2 pi()R * cos(45) / (24*60*60) )
dV/ dx = dV/d theta * d theta /dx
