A 1.5-kg mass attached6b+ o .0viwjoa to spring with a force constant of 20.0 N/m oscillate ur7zvt8no45o0+u jxo88n oi3hah 6z :rn-wnvs on a horizontal, frictionless track. At t= 0, the mass is released from rest at x= 10.0 cm. (That :ornr87o zon v5nwhz8n+-oh80ux 4 v 3atjiu6is, 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 = $0.10 \; \cos (3.7t)$
