Question

A hockey puck oscillates on a frictionless, horizontal track while attached to a horizontal spring. The puck has mass 0.160 kg and the spring has force constant 8.00 N/m. The maximum speed of the puck during its oscillation is 0.350 m/s. What is the amplitude of the oscillation? What is the total mechanical energy of the oscillation? What is the potential energy of the puck when the displacement of the glider is 0.0300 m? What is the kinetic energy of the puck when the displacement of the glider is 0.0300 m?

Answer 1

mass (m) = 0.160kg spring constant (K) = 8 Nim maximum speedrun) = 0.35 mys .: Angular frequency (we, was W=7.07 vode Vmaxe = AW =) A = Vman A = 0.35 = À 30.05m = Amplitude (-) = 0.05 meter 7.07 M.E=4k4 = = * 8x10.05)2 TME = 9.8*103 Joule fur x =0.03, P.E - £k{"> _*8*10.03)? > PE = 3.6*0035 KEE M.E.-P.E.
