Page 1 Name: __________________________ Date: _____________ 1. The force constant of a massless spring is 25.0 N/m. A mass of 0.45 kg is oscillating in simple harmonic motion at the end of the spring with an amplitude of 0.32 m. The maximum speed of the mass is A) 5.7 m/s B) 56 m/s C) 7.4 m/s D) 2.4 m/s E) 10 m/s 2. A spring vibrates in simple harmonic motion according to the equation x = 0.15 cos π t where the units are SI. The period of the motion is A) 0.67 s B) 1.0 s C) 2.0 s D) s E) 3.2 s 3. A clock keeps accurate time when the length of its simple pendulum is L . If the length of the pendulum is increased a small amount, which of the following is true? A) The clock will run slow. B) The clock will run fast. C) The clock will continue to keep accurate time. D) The answer cannot be determined without knowing the final length of the pendulum. E) The answer cannot be determined without knowing the percentage increase in the length of the pendulum. 4.
