• The displacement of particle executing simple harmonic motion is represented by y = r sin .  Find the velocity and acceleration of particle in terms of displacement.
• Show that if acceleration of particle at extreme position is twice the magnitude of velocity at mean position, then time period of oscillation of particle is π s.

• Two particles A and B execute simple harmonic motions given by the equations y_A = 10 sin 12 and y_B = 12 sin 10 Which has greater velocity at mean position?
• A particle is executing simple harmonic motion.  What is phase relationship between velocity and acceleration?
• Show that for a particle in linear simple harmonic motion, the average kinetic energy over a period of oscilllation is half the total energy.
• A spring of force constant 1200 N/m is mounted on a horizontal table. A mass of 30 kg is attached to the free end of the spring, pulled side ways to a distance of 2.0 cm and released. (a)  What is the frequency of oscillation of the mass? (b)  What is the maximum acceleration of mass? (c)  What is the maximum speed of mass?
