assuming birdman flies at a speed of 22 m/s how high should birdman fly to hit the bucket if the bucket is placed 92 m from the
1 answer:
Answer:
I will suppose that: The initial velocity of the birdman is horizontal. Now, the only force acting on birdman will be the gravitational force, so we can write the acceleration of birdman as

Answer:
Approximately of steam at
(assuming that the boiling point of water in this experiment is
.)
Explanation:
Latent heat of condensation/evaporation of water: .
Both mass values in this question are given in grams. Hence, convert the specific heat values from this question to .
Specific heat of water: .
Specific heat of copper: .
The temperature of this calorimeter and the of water that it initially contains increased from
to
. Calculate the amount of energy that would be absorbed:
.
.
Hence, it would take an extra of energy to increase the temperature of the calorimeter and the
of water that it initially contains from
to
.
Assume that it would take grams of steam at
ensure that the equilibrium temperature of the system is
.
In other words, of steam at
would need to release
as it condenses (releases latent heat) and cools down to
.
Latent heat of condensation from of steam:
.
Energy released when that of water from the steam cools down from
to
:
.
These two parts of energy should add up to . That would be exactly what it would take to raise the temperature of the calorimeter and the water that it initially contains from
to
.
.
Solve for :
.
Hence, it would take approximately of steam at
for the equilibrium temperature of the system to be
.
