The change in potential energy of an object is given by
where
m is the mass of the object
g is the gravitational acceleration
is the increase in altitude of the object
In our problem,
is the mass of the book, 
and
is the increase in altitude of the book, so its variation of potential energy is
where
m is the mass of the object
g is the gravitational acceleration
In our problem,
This is what it would look like—
Angular velocity = w
Linear velocity = v
Centripetal acceleration = ac
Angular velocity = w
Linear velocity = v
Centripetal acceleration = ac
Answer:
a.) Speed V = 29.3 m/s
b.) K.E = 1931.6 J
