Physics II QUIZ 9: Simple Oscillator 96. A hand spring scale stretches 3.1 cm from equilibrium when a fish is suspended from it. What is the mass of the fish if the spring constant of the scale is 635 N/m? (A) 2009 kg (B) 20. kg (E) 0.193 kg (C) 193 kg (D) 2.0 kg 97. A mass of 300.0 g is suspended from a spring with a spring constant of 40.0 N/m. When this mass is pulled down 3 mm and set in oscillation, what is the amplitude of the oscillation? (A) 3 mm (E) 5 cm (B) 1.5 cm (D) 5 mm (C) 4 cm 98. A certain mechanism has a part acting as a simple harmonic osc ator. It includes a spring with a spring constant N/m and a mass 72 g is necessary to decrease the period of the oscillation by a factor of 3 without changing the spring, but only by adjusting the attached mass. What should the adjusted mass be? (E) 650 g (D) 300 g (C) 19.0 g. (A) 8.0 g (B) 24.0 g 99. Two identical weights are suspended from two different springs. One spring is stiff (high spring constant) and another is weak (low spring constant When both weights are set in oscillation, which one has a greater period of oscillation? (A) Suspended from the stiff spring (B) Suspended from the weak spring (C) Neither one (D) Insufficient information 100. identical weights are suspended from different springs. One spring is stiff (high spring which Two weights are set in oscillation, constant) and another is slender (low spring constant). When both one has a greater frequency? (A) Suspended from the stiff spring (B) Suspended from the slender spring (C) Neither (D) Insufficient information

Explanation / Answer

Spring constant k = 635 N/m

Streachness X = 3.1 cm = 3.1 x10 -2 m

Mass of the fish M = ?

At equilibrium , weight of the fish = kX

Mg = kX

From this mass of the fish M = kX / g

M = (635x3.1x10 -2) / 9.8

= 2.008 kg

= 2.0 kg ( two significant figures)
