The tangential velocity of the ball is 0.63 m/s.
<h3>
What is tangential speed?</h3>
Tangential speed is the linear component of the speed of any object moving along a circular path.
v = ωr
where;
- v is the tangential speed
- ω is the angular speed (rad/s)
- r is the radius of the circle
At a given radius of the circle = 0.3 m
Let the number of revolution per min = 20 rev/min
v = ωr
v = 2.1 x 0.3
v = 0.63 m/s
Thus, the tangential velocity of the ball is 0.63 m/s.

Your velocity forward in would be 1.66 m/s. to solve you would use the velocity equation.
In a transformer, energy is carried from the primary coil to the secondary coil by magnetic field in the iron core.
To find the answer, we have to know more about the transformer.
<h3>
How transformer works?</h3>
- An item utilized in the transfer of electric energy is a transformer.
- AC current is used for transmission.
- It is frequently used to modify the supply voltage between circuits without altering the AC frequency.
- The fundamentals of mutual and electromagnetic induction govern how the transformer operates.
- Magnetic field through the primary coil changes when primary coil current varies. the iron core of the secondary coil likewise has a magnetic field.
- EMF is therefore generated in the secondary coil.
Thus, we can conclude that, in a transformer, energy is carried from the primary coil to the secondary coil by magnetic field in the iron core.

In order to develop this problem it is necessary to use the concepts related to the conservation of both potential cinematic as gravitational energy,
Where,
M = Mass of Earth
m = Mass of Object
v = Velocity
r = Radius
G = Gravitational universal constant
Our values are given as,
Replacing we have,
Therefore the speed of the object when striking the surface of earth is 4456 m/s
