# Oscillations and Simple Harmonic Motion

### Problems

Problem : At what point during the oscillation of a spring is the force on the mass greatest?

Problem : What is the period of oscillation of a mass of 40 kg on a spring with constant k = 10 N/m?

Problem :

A mass of 2 kg is attached to a spring with constant 18 N/m. It is then displaced to the point x = 2 . How much time does it take for the block to travel to the point x = 1 ?

Problem :

A 4 kg mass attached to a spring is observed to oscillate with a period of 2 seconds. What is the period of oscillation if a 6 kg mass is attached to the spring?

Problem :

A mass of 2 kg oscillating on a spring with constant 4 N/m passes through its equilibrium point with a velocity of 8 m/s. What is the energy of the system at this point? From your answer derive the maximum displacement, x m of the mass.
