APFIVE SHM Velocity and Acceleration
A particle undergoes SHM with amplitude A and angular frequency ω. If the particle is at position x = A/2 at a certain instant, what can be concluded about its velocity and acceleration at that instant?
A
v ≠ 0, a = -ω²A/2
B
v = ±ωA/√2, a = 0
C
v ≠ 0, a = 0
D
v = 0, a = -ω²A/2
