Maximum acceleration with zero velocity is possible only for:
Correct answer: C. Simple Harmonic Motion
- A. Non inertial frame of reference
- B. Rotational motion
- C. Simple Harmonic Motion
- D. Random Motion
Explanation
Option A: In non-inertial frames of reference, such as those that are accelerating or rotating, the laws of motion are different. In these frames, it is possible for an object to have a maximum acceleration with zero velocity. However, this is not a natural phenomenon, and it can only occur in special circumstances. Option B: In rotational motion (linear or non-linear), the maximum acceleration is not associated with zero velocity. In rational motion, the acceleration and velocity may vary independently, and there is no specific relationship between the two that guarantees maximum acceleration with zero velocity. Option C: At the extreme points of SHM, the displacement is maximum, and the object momentarily comes to rest before changing direction. At these points, the acceleration is maximum, but the velocity is zero. The acceleration is zero at the equilibrium position. Optio D: Random motion is a type of motion that is not periodic or predictable. It is not possible for an object to have a maximum acceleration with zero velocity in random motion.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.

A first harmonic stationary sound wave is produced in the air of a cylinder that is half-filled with water. More water is added to the cylinder. Now the first harmonic stationary wave is produced with a different frequency. What are the changes in frequency and the nature of displacement in the air at the water surface?
