Hi there!
We can use the derived equation to solve:
, where:
h = height
g = acceleration due to gravity
Plug in the given values. Remember to CONVERT km to m:
32 km = 32 km * 1000 m / 1 km = 32,000 m
t = √(2(32000)/3.4) ≈ <em>137.199 sec</em>
Part 2:
Use the derived equation:
vf = √2gh
vf = √(32000)(3.4) = <em>329.848 m/s</em>

Answer:
The store energy is 2113109.72 J.
Explanation:
Given that,
Radius = 0.11 m
Mass = 6.5 kg
Spins = 70000 rpm
Suppose we need to find how much kinetic energy is stored by the flywheel when it is rotating at its maximum rate
We need to calculate the moment of inertia
Using formula of moment of inertia
Put the value into the formula
We need to calculate the rotational kinetic energy
Using formula of rotational kinetic energy
Put the value into the formula
Hence, The store energy is 2113109.72 J.
