The acceleration a1 of the block when it passes through its equilibrium position is 0 .
What is Acceleration ?
Acceleration cab be defined as rate of change of velocity with time .
we know that by Hooke's Law , The restoring force in case of simple harmonic motion is an elastic force of the spring ,
that is ; F = -k*x .
Substituting the value of Force = ma in the equation ,
we get ,
ma = -kx
So , acceleration (a) will be
a = -kx/m
Now , when the body is in equilibrium , the displacement (x) is 0 .
So , a = -k(0)/m
a = 0 .
Therefore , the acceleration is 0 .
