Chapter J - Problems Blinn College - Physics 2425 - Terry Honan Problem J.1 The position as a function of time for a particle in simple harmonic motion is x H t L = H 4 cm L cos AI 3 p s - 1 M t +p E . (a) What are the period and frequency? (b) What is the amplitude of the oscillation? (c) What is the phase angle? (d) What is the maximum speed and maximum acceleration? (e) At t = 0.25 s what is the position of the particle? (f) Suppose this describes the postion of a 0.6 kg mass at the end of a spring. What is the spring constant? Problem J.2 When a mass is hung from a spring is stretches it by 15 cm. What is the period of the oscillations of this system? Problem J.3 A .5 kg mass oscillates witn an amplitude of 10 cm at the end of a spring with spring constant of 8 N ê m (a) What are the maximum speed and acceleration? (b) What are the speed and acceleration of the mass when it is 6 cm from the equilibrium position? (c) How long does it take for the mass to move from eqilibrium to 6 cm from equilibrium?
