Question

For a body executing SHM with amplitude A, time period T, maximum velocity vₘₐₓ and phase constant zero, which statements are correct?

G1 Physics · Accepted Answer

At y=A/2, v=vₘₐₓ√(1−1/4)=√3 vₘₐₓ/2>vₘₐₓ/2. If v=vₘₐₓ/2, then |y|=√3A/2>A/2. At t=T/8, y=A/√2>A/2. Starting from mean with zero phase, y=A/2 first occurs at T/12<T/8. Hence A, B, C and D are all correct.
