A particle of mass \(4 \mathrm{~kg}\) is executing SHM. Its displacement is given by the equation \(y=8 \cos [100 t+\pi / 4] \quad \mathrm{cm}\). Its maximum kinetic energy is
- A \(128 \mathrm{~J}\)
- B \(64 \mathrm{~J}\)
- C \(16 \mathrm{~J}\)
- D \(32 \mathrm{~J}\)
Answer & Solution
Correct Answer
(A) \(128 \mathrm{~J}\)
Step-by-step Solution
Detailed explanation
Equation of particle executing SHM \[ y=8 \cos \left[100 t+\frac{\pi}{4}\right] \mathrm{cm} \] Here, \(\quad \omega=100 \mathrm{rad} / \mathrm{s}, a=8 \mathrm{~cm}\)…
