QUESTION:
The point of the needle of a sewing machine moves in SHM along the x -axis with a frequency of 2.5 Hz. At t = 0 its position and velocity components are + 1.1 cm and - 15 cm/s, respectively. (a) Find the acceleration component of the needle at t = 0. (b) Write equations giving the position, velocity, and acceleration components of the point as a function of time.
ANSWER:Solution 13E Step 1: Introduction : We need to find the acceleration of the needle at time t = 0 In the second part we need to write the function of the time with position, velocity and acceleration components of the time
