The vertical speed of the rod varies inversely as the rotational speed for a given number of complete rotations
The equation that gives the vertical velocity, v₀ is 
Reason:
<em>From a similar question, the given parameters appear to be correctly given as follows;</em>
<em>The vertical speed of the rod = v₀</em>
<em>Angular velocity of the = ω₀</em>
Required;
The value of, v₀, so that the rod has made exactly, <em>n</em>, number of turns when it returns to his hand
Where;
n = An integer
Solution;
The time the rod spends in the air is given as follows;
Where;
g = Acceleration due to gravity
t = Time of motion
When the rod returns to his hand, we have, h = 0, therefore;
We have;
Therefore;

What does "a 4-inch candle" mean ?
Is that the length of the candle or its diameter ?
The life of a candle depends on its length, its diameter, the
thickness and starting-length of its wick, the exact substance
of which it's composed ... the type of wax ... and the motions
of the air around it.
I'll always remember the candle shop I visited ... I don't remember
what I was doing in a candle shop, but I was there. There was a
little wax turkey up on a glass shelf, with a tiny tiny flame in the
middle of its back, so tiny that you could easily miss noticing it.
The little sign standing next to the little turkey on the shelf explained
that this was a Thanksgiving candle ... it was lit last Thanksgiving,
and would continue burning until NEXT Thanksgiving, roughly a year later !
The distance is 1760 km
The speed is 960 km hour I.e 960 divide by 60 = 16 km/minute
hence in time 1 hour 50 minutes I.e 110 minutes
distance travelled is 110 - 16 = 1760 km
