A particle oscillates so that its displacement x from a fixed point is related to time t by the equation
x = 3 \sin(5\pi t).
If x is measured in \text{cm} and t is measured in \text{s}, we can deduce that the particle
I. moves with Simple Harmonic Motion
II. has a frequency of 2.5\text{ Hz}
III. has an amplitude of 1.5\text{ cm}
- (A)I and II only
- (B)I, II and III
- (C)II and III only
- (D)III only
