Questions
The displacement of a particle varies with time as x = 12 sin - 16 (in cm). If its motion is S.H.M., then its maximum acceleration is
detailed solution
Correct option is B
x = 12 sin ωt - 16 sin3 ωt = 4[3 sin ωt - 4 sin3 ωt]= 4[sin 3 ωt](By using sin 3θ = 3 sin θ -4 sin3θ)∴ maximum acceleration Amax = (3ω)2×4 = 36ω2Talk to our academic expert!
