A 1.5-kg mass attached to spring with a force constazexxg*xc 2.vac3n, 6znt ofk(1d4 i7:casj 6 b8vx*crhezk 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 stretched bievk *61cbkjxzra(c:sdh 78 4 y 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 = $0.10 \; \cos (3.7t)$
