[填空题]
A 300-g mass vibrates according to the ei,.c87oy5wld fu7l hoquation x = 0.38sin6.5t wh ;0 0k op g38/tigkrkiqtsh,8 i3dbq-here x is in meters and t is in secoi 800htqo;gh3i/d t,qgbk 3r-pk 8iksnds. Determine
(a) the amplitude,    m
(b) the frequency,    Hz
(c) the period,    s
(d) the total energy, $\approx$    J
(e) the KE and PE when x is 9.0 cm.$E_{potential}$ =    J $E_{kinetic}$ =    J($E_{kinetic}$round to two decimal place)
(f) Draw a careful graph of x vs. t showing the correct amplitude and period.
