The position, velocity and acceleration of a particle executing simple harmonic motion are found to have magnitudes of 4 m, 2 ms-1 and 16 ms-2 at a certain instant. The amplitude of the motion is x m where x is .
Answer
17
Solution
|a| = 2 y 16 = 2 4 = 2 rad s-1
v = A2 - y2 2 = 2 A2 - 16
A2 = 17, so A = 17 m
x = 17
Answer: 17
