It is given that the amplitude of the motion,
A=2x0 The time required to distance from compressed position to
mean position is
‌ The displacement from mean position,
y=A‌sin‌ω‌t and
x0=2x0‌sin‌ω‌t x0=2x0‌sin‌t sin‌=sin‌t t=‌ Thus, the time taken to hit the wall,
‌+‌=‌ Or The expression for the time period is,
T=2π√‌ So, the time taken to hit the wall is calculated as,
‌=‌√‌
