For a body in S.H.M. the velocity is givenby the relation V-144 -16x2 ms'. Themaximum acceleration is1) 12 m/s 2) 16m/s 3) 36m/s 4) 48m/s2 211. |

Answer» The expression of velocity in S.H.M is V² = ω²(a² -x²) here.. a = maximum amplitude and ω is the frequency.. so, compraing V = √144-16x² = √(12)²-(4x)² , we get ω (as coefficients of x)= 4 and a as √9 = 3m so, maximum acceleration is aω² = 3*4*4 = 48m/s² so option D. |
