In which of the following scenarios will the K.E be zero?
Correct answer: D. All of these
- A. At maximum height when a ball is thrown upwards
- B. At extreme position of a Simple Pendulum
- C. At the amplitude of the Mass Spring System
- D. All of these
Explanation
Kinetic energy (KE) is the energy possessed by an object due to its motion. It is given by the formula:KE = (1/2) * mv^2where:m is the mass of the objectv is the velocity of the objectIn all the given scenarios, the object is momentarily at rest, meaning its velocity (v) is zero. Therefore, the kinetic energy (KE) will be zero in all these cases.

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.
