Question

The graph shows the x-displacement as a function of time for a particular object undergoing simple harmonic motion. (w) x 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 t (s) This function can be described by the following formula: x(t) = Acos(wt), where x and A are measured in meters, t is measured in seconds, w is measured in rad/s. Using the graph determine the angular frequency w of the oscillation. 1.5 m/s Submit Answer Incompatible units. No conversion found between "m/s" and the required units. © Tries 0/12 Previous Tries

Explanation / Answer

Omega=2/T

By this graph T=4.5s( timeperiod for one complete wave)

Which is approximately equal to 4.5 sec

Omega=1.4 rad/s
