When you throw the ball in the air it is considered kinetic energy. Once the ball reaches its max height, it stops moving and all kinetic energy turns into potential energy. So when the ball is at its highest point.

Answer: rp/re= me/mp= 544 * 10^-6.
Explanation: To calculate this problem we have to consider the circular movement by the electron and proton inside a magnetic field.
Then the dynamic equation for the circular movement is given by:
Fcentripetal= m*ω^2.r
q*v*B=m*ω^2.r
we write this for each particle then we have the following:
q*v*B=me* ω^2*re
q*v*B=mp* ω^2*rp
rp/re=me/mp=9.1*10^-31/1.67*10^-27=544*10^-6
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.
