A sewing machine needle moves with a rapid oscillatory motion, essentially in simpleharmonic motion, as it sews a seam. Suppose the needle moves 9.5 mm from its highest to itslowest position as it makes 36 stiches in 8.0 s. (a) What is the angular frequency, o, of theneedle? (b) What is the maximum speed of the needle? (c) What is the magnitude of themaximum acceleration of the needle? (d) Include a diagram of the situation that indicateswhere the location of the maximum speed and acceleration are located in the motion of theneedle. [
