Much energy as would Microraptor gui have to expend to fly with a speed of 10 m/s for 1.0 minutes is 486 J.
The first step is to find the energy that Microraptor must release to fly at 10 m/s for 1.0 minutes. The energy that Microraptor must expend to fly can be found using the relationship between Power and Energy.
P = E/t
Where:
P = power (W)
T = time (s)
Now, a minimum of 8.1 W is required to fly at 10 m/s. So, the energy expended in 1 minute (60 seconds) is
P = E/t
E = P x t
E = 8.1 x 60
E = 486 Joules
Thus, the energy that Microraptor must expend to fly at 10 m/s for 1.0 minutes is the 486 J.

The angular acceleration of the potter's wheel is 0.067 rad/s².
The given parameters:
- Final angular speed, ωf = 0.4 rev/s
- Time of motion, t = 37.5 s
<h3>What is angular acceleration?</h3>
- Angular acceleration of an object is the rate of change of angular speed of the object.
The angular acceleration of the potter's wheel is calculated as follows;
Thus, the angular acceleration of the potter's wheel is 0.067 rad/s².
