mass and the other to a rigid support is stretchedthey A spring with one end attached to a mass andreleased. When is the magnitude of acceleration a maximum?and

Answer»

When the spring (having spring constant=k) is stretched by length x, restoring force will beF = -kxHere, -ve sign shows that force is always in direction opposite to displacement.

The restoring force is central, hence particle will move in S.H.M. about equilibrium position.Acceleration here is given bya = F/m = -kx/m

When just released x = x(max).Hence a = a(max).

Hence, acceleration will be maximum when spring is just released.
