Physics - SHM Question with Solution | TestHub

Amplitude, $\mathrm{A} = 0.06 \mathrm{m}$
Frequency, $\mathrm{f} = 15 \mathrm{Hz}$
Maximum velocity of the body,

${\text{v}}_{\text{m}}=\omega \text{A}$

$=\left(2\pi \text{f}\right)\text{A}$

$=2\times \text{3.14}\times 15\times \text{0.06}$

$= 5.65 \mathrm{m} {\mathrm{s}}^{-1}$ 

Maximum acceleration of the body.

${\text{a}}_{\text{m}}={\omega }^2\text{A}$

$={\left(2\pi \text{f}\right)}^2\text{A}=4{\pi }^2{\text{f}}^2\text{A}$

$=4\times {\left(\text{3.14}\right)}^2\times 15^2\times \text{0.06}$

$=\text{5.32}\times 10^2 {\text{m s}}^{-2}$
