Question:
A spring with one end attached to a mass and the other to a rigid support is stretched and released.
(a) magnitude of acceleration, when just released is maximum
(b) magnitude of acceleration, when at equilibrium position is maximum
(c) speed is maximum when mass is at equilibrium position
(d) magnitude of displacement is always maximum whenever speed is minimum
Solution:
The correct answer is (a) magnitude of acceleration, when just released is maximum and (c) speed is maximum when mass is at equilibrium position
