Chapter 15, Problem 009 CZ Your answer is partially correct. Try again. The function x 4.9 m) cos[(4arrad/s)t ir/3 rad gives the simple harmonic motion of a body. Att 7.9 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 4.73 units (b) Numbe 15.8 Units T m/s (c) Number 1747 Units m/s 2 (d) Numbe p9.9 Units Trad (e) Number 2.00 units Unit a (f) Number T0.510 Click if you would like to show work for this question Open Show Work

Explanation / Answer

Velocity is calculated as follows
