Answer:
Period remains the same, Max KE increases, Max acceleration is the same
Explanation:
The period, kinetic energy, and acceleration of the new pendulum will remain the same.
[tex]T = 2\pi\sqrt {\dfrac lg}[/tex]
Where,
[tex]T[/tex]- Period
[tex]l[/tex] - length of string
[tex]g[/tex] - gravitational acceleration
From the equation, the period of the pendulum does not depend upon the density of the pendulum or sphere.
Therefore, the period, kinetic energy, and acceleration of the new pendulum will remain the same.
