The function x=(9.1 m) cos[(4rad/s)t +/5 rad] gives the simple harmonic motion of a body. At t = 1.9 s, what are the (a) displacement, (b) velocity, (c) acceleration, and (d) phase of the motion? Also, what are the (e) frequency and (f) period of the motion? (a) Number Units m (b) Number Units m/s (c) Number (d) Number i Units m/s^2 Units rad The function x=(9.1 m) cos[(4rad/s)t +/5 rad] gives the simple harmonic motion of a body.
