Answer:
Explanation:
x ( t ) = sin ( π 10 t )
This is the equation of a simple harmonic motion .
standard equation of simple harmonic motion is as follows
x ( t ) = A sin ωt , A is amplitude , and ω is angular frequency .
The angular frequency ω = 10π
If time period be T
ω = 2π / T
10π = 2π / T
T = 2π / 10π
T = .2 s .
Time period = .2 s .
