Let's see
Now we know the formula of acceleration
Or
At high altitudes, the air pressure is lower and it is more difficult for us to breathe because we cannot take in enough oxygen.
To solve the problem, it will be necessary to define the rotational and translational kinetic energy in order to determine the relationship between the two. Rotational energy is defined as,
Here,
I = Moment of Inertia
= Angular velocity
Now the translational energy will be,
Here,
m = Mass
v = Velocity
Therefore the relation between them will be,
Applying the moment of inertia of a sphere we have,
Therefore the ratio will be 0.01077
Answer:
300 m/s
Explanation:
As the cylinder drops off so its initial velocity is zero.
h = 4500 m, g = 10 m/s^2, u = 0
Use third equation of motion
v^2 = u^2 + 2 g h
v^2 = 0 + 2 x 10 x 4500
v^2 = 90000
v = 300 m /s
The force of gravity most likely
