Question

QUESTION 10 When a 200 g mass attached to a horizontal spring (k= 25 N/m) is pushed 10 cm into the spring and released, it undergoes simple harmonic motion. Find the quantities below for this oscillating system: (a) The angular frequency (rad/sec) QUESTION 11 When a 200 g mass attached to a horizontal spring (k-25 N/m) is pushed 10 cm into the spring and released, it undergoes simple harmonic motion.

Colution dirt tee if you understood the solution!! Olo 2009: 0.gooley K= 250lm A= 10cm. o.lom For harmonic oscillation, angular frequency is given as, putting valus J 25 = 11:18 gead/s 0:200 (6) Period goscillation, T = 27 putting values, TE 2T 0.562 sec 11'16 8 = We know, frequency, Jeuquency, 8 st 1 Time period (7) 1.78 Hz d) Marrimum speed will be at mean position and is given by Iman = Aw= 0.1ox 11 18 lill&m's - Iman Masumum acceleration will be at maximum alisplacement from mean, (11.18) ² x (0.10) amax = aman= 12.5m/34 WA
