A particle has SHM with x = A cos(ωt). At t = 0, the particle is at:
Ax = A/2
BRandom
Cx = A (extreme position, v = 0)
Dx = 0 with maximum velocity
Answer & Solution
Correct answer: C. x = A (extreme position, v = 0)
At t = 0: x = A cos(0) = A. So particle starts from extreme position (x = A). Velocity v = -Aω sin(ωt), at t=0 is 0. Particle starts from rest at maximum displacement.
