A 1.5-kg mass attached to spring wtcq- )mqr vhlg912oa 6ith av+(26x cmabwvop0 2we force constant of 20.0 N/m oscillates on a horizontal, frictionless track. At t= 0, the mass is released from rest at x= 10.0 cm. (That is, the spring is sw+2eo b 2(0mcax6vpvwtretched 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 = $0.10 \; \cos (3.7t)$
