Question

A simple harmonic motion having an amplitude $A$ and time period $T$ is represented by the equation : $y = 5 \sin \pi (t + 4) m$
Then the values of $A$ (in m) and $T$ (in sec) are :

• A. A = 5; T = 2
• B. A = 10 ; T = 1
• C. A = 5 ; T = 1
• D. A = 10 ; T = 2

Answer 1

Answer: (A)

$A =5, \omega=\pi=\frac{2 \pi}{ T }, T =2$
