Answer:
Time period for Simple pendulum, 
Explanation:
The Simple Pendulum
Consider a small bob of mass
is tied to extensible string of length
that is fixed to rigid support. The bob is oscillating in the plane about verticle.
Let
is the angle made by string with vertical during oscillation.
Vertical component of the force on bob,
Negative sign shows that its opposing the motion of bob.
Taking
as very small angle then, 
Let
is the displacement made by bob from its mean position ,
then, 
so,
........(1)
Since, pendulum is in hormonic motion,
as we know, 
where
is the constant and 
.........(2)
From equation (1) and (2)


Since, 


Answer:
A change in velocity is either a change in an object's speed or its direction. When a moving object changes direction, its velocity changes and it is accelerating.
Explanation:
Answer:
Explanation:
Given
at certain point displacement and velocity is 0.345 m and 0.54 m/s
Therefore Potential and Kinetic Energy associated is



Kinetic Energy 

Total Energy 
Total Energy is conserved hence at maximum displacement all energy will be Potential energy

where A=maximum displacement



Maximum speed occurs at equilibrium Position where Potential Energy is zero
thus 


(c)When block is at 0.2 m from Equilibrium speed then its Potential Energy is
