Question

The displacement equation of an oscillating particle is as follows y = 0.7 sin ( 50 pie t + 30 o  ) where distance are in cm and time is in seconds. Find the amplitude,  frequency, phase angle and period of the particle.​

Answer 1

Answer:

(A)x=5sin(4πt+arctan(4/3)) so motion is simple harmonic

(B)T=2π/4π=0.5

(C)x=5sin(4πt+arctan(4/3)) so amplitude is 5mm

(D) at t=0,x
