A
hot-air balloon is initially floating (stationary) a few metres
above the ground. The radius of the spherical balloon is 6.25 m,
and the density of surrounding air is 1.29 kg m-3. "Ballast" is
weight of negligible volume that can be dropped to make the balloon
rise. How much weight would you have to drop overboard to make the
balloon rise 105 m in 15.0 s? You may assume that the density of
surrounding air remains constant.

A coin is dropped from a hot-air balloon that is 287.3m above
the ground and rising at 10.0m/s upward. For the coin, find: a) the
maximum height reached,b) its position 4.34s after being
released,c) and the time before it hits the ground.

A hot air balloon has a volume of 65,00 cubic feet of hot air.
The balloon is at sea level on a standard day. If the temperature
of the hot air in the balloon is 1100F, determine the
lifting force of the balloon.

How hot is the air in the top (crown) of a hot air balloon?
Information from Ballooning: The Complete Guide to Riding the
Winds, by Wirth and Young (Random House), claims that the air in
the crown should be an average of 100°C for a balloon to be in a
state of equilibrium. However, the temperature does not need to be
exactly 100°C. What is a reasonable and safe range of temperatures?
This range may vary with the size and...

A hot air balloon has a volume 3,223 m3 . It is
filled with hot air of density 0.96 kg/m 3 . The total mass of
cabin, envelope etc is 350 kg. Find the maximum load of the balloon
in Newtons if the density of surrounding air is
1.29kg/ m3
Use g = 9.8 m/s2 Calculate answer to one decimal.
