Question

A body executes simple harmonic motion according to the following equation;

\(x = 5.0 cos[2 \pi t + \frac{\pi}{4}]m\)

where t = 1.5 s, calculate (i) displacement (ii) velocity (iii) acceleration.

Answer 1

(ii) From the given equation.

Amplitude a = 0.5m; angular speed \(\omega_0 = 2\pi \; rad\; s^{-1}\)
