Determine the volume (m^3) necessary to fill with hot air for a
hot air balloon to lift a payload of 800 kg. Assume that the
temperature inside the balloon is 99.0 C and the temperature
outside is 20.0 C. Assume that the pressure (inside and out) is
1.00 atm and that the molar mass of air is 28.9 g/mol.

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.

A hot-air balloon is drifting in level flight due east at 2.9
m/s due to a light wind. The pilot suddenly notices that the
balloon must gain 26 m of altitude in order to clear the top of a
hill 120 m to the east.
GIVENS:
How much time does the pilot have to make the altitude change
without crashing into the hill? = 41s
What minimum, constant, upward acceleration is needed in order
to clear the hill? = 3.0*10^-2m/s^2...

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.

(8pts) A hot air balloon moves up at constant speed v = 20.0
m/s. When the balloon is 20.0 meter above the ground, a cup of
lemonade falls out of the balloon. And the balloon continues to
move up at a constant speed v = 20.0 m/s. Ignore the air
resistance.(a)Describe the motion of the lemonade cup as relative
to the ground.(b)Describe the motion of the lemonade cup as
relative to the balloon. (c)On the same diagram,plot thev-t graph

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.

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...
