A hot-air balloon of diameter 12 m rises vertically at a constant speed of 11 m/s . A passenger accidentally drops his camera fr
1 answer:
To solve this problem we will apply the linear motion kinematic equations. First we will determine the time it takes for the camera to fall to the floor. Later with that time, we will calculate from the initial position when the balloon ascended.
Here
= Initial velocity
g= Acceleration due to gravity
t = time
Replacing with our values
Solving for the time,
Now with the previous position we have that the balloon has ascended around to,

To solve this problem it is necessary to apply the equations related to the Force of Friction and Energy.
By definition the friction force is defined as
Where,
Frictional Constant
N = Normal Force -> mg
At the same time we have the definition of the Energy, which can be
E = F*v
Where,
Force
v = Velocity.
Then replacing with our values we have that,
F = 0.5 *34
F = 17
The energy then would be,
E = f v
E = 17 * 0.30 = 5.1 W
Therefore the rate at which heat is generated is 5.1W
