10PRACTICE PROBLEM
A mechanical oscillator consists of a block of mass m and a spring of force constant k. Placed on a smooth horizontal table, the block undergoes simple harmonic motion with an amplitude 30 cm and frequency 0.5 Hz. At the position x = 20 cm, what are i) the speed (v) and ii) the acceleration of the object (ax)?
