Question

2. The needle point in a sewing machine moves in Simple Harmonic Motion with
frequency of 2.2Hz . At t=0 , the position of the needle is at 1.0cm and the
velocity is -12cm/s.
A. What is the equation of motion of the needle point?
B. What is the acceleration at t=0s?

Definition Definition Special type of oscillation where the force of restoration is directly proportional to the displacement of the object from its mean or initial position. If an object is in motion such that the acceleration of the object is directly proportional to its displacement (which helps the moving object return to its resting position) then the object is said to undergo a simple harmonic motion. An object undergoing SHM always moves like a wave.
