A bullet with mass 5.29 g is fired horizontally into a 2.192-kg block attached to a horizontal spring. Thespring has a constant 5.62 x 102 N/m and reaches a maximum compressionof 5.83 cm.
(a) Find the initial speed of the bullet-block system.
m/s
(b) Find the speed of the bullet.
The transverse displacement (y) of a wave is given as a function of position (x in meters) and time (t in seconds) by the expression to the right. Determine the wavelength, frequency, period, and phase constant of this waveform.
Excited states do not in general live very long before they decay.Suppose a certain excited state lives just 10^-7 s. In that case weknow the time when the atom is in the excited state quiteaccurately--to within ?t=10^-7 s. That means there is a ..
