A 1.5-kg mass attachear h5nqr*+crgb gzyr0a/ -sc- n-9 4yco9(gmmcmnnk8w2p9 iy a +7+vwd to spring with a force constant of 20.0 N/m oscillates on a horizontal, fric+gwn7n 9 comvpka8 miy+ 9w2m(tionless track. At t= 0, the mass is released from rest at x= 10.0 cm. (That is, the spring is stretched by 10.00 cm.)
(a) Determine the frequency of the oscillations.
(b) Determine the maximum speed of the mass. Where does the maximum speed occur?
(c) Determine the maximum acceleration of the mass. Where does the maximum acceleration occur?
(d) Determine the total energy of the oscillating system.
(e) Express the displacement as a function of time.
参考答案:
(a) 0.58 Hz
(b) 0.37 m/s, at the equilibrium position
(c) $1.3 \; m/s^2$, at maximum displacement
(d) 0.10 J
(e) x = $0.10 \; \cos (3.7t)$
