Answer:
The centripetal acceleration, 
Explanation:
Centripetal acceleration is given by the formula:
Where the speed of the ball, v = 16 m/s
Length of the string, r = 0.2 m
Substituting these parameters into the centripetal equation above:

I think it is better if you read and shortly write my explanation
Explanation:
simple pendulum with no friction, mechanical energy is conserved. Total mechanical energy is a combination of kinetic energy and gravitational potential energy. As the pendulum swings back and forth, there is a constant exchange between kinetic energy and gravitational potential energy.
