Problem 5: Consider a particle moving in uniform circular motion in the xy plane at a distance r = 1.1l m from the origin. Refer to the figure. In this problem, you will show that the projection of the particle's motion onto the x-axis can be used to represent simple harmonic motion. Part (a) If the particle moves counterclockwise at a constant angular velocity of w, and at timet 0 its coordinates are (x,y) = (r,0), enter an expression for the projection of the particle's position onto the x-axis, in terms of r, w, and t. Expression : Select from the variables below to write your expression. Note that all variables may not be required. cos(a), cos(ot), cos(o), cos(0), sin(a), sin(ot), sin(4), sin(0), a, o, 0, g, m, r, t Part (b) For an angular speed of w = 2.1 rad/s, find the value of x, in meters, at time t= 0.22 s. Numeric : A numeric value is expected and not an expression. Part (c) Considering the expression you entered in part (a) for the projection of the particle's position onto the x-axis, can the projection's motion be described as simple harmonic motion? MultipleChoice : 1) No 2) Yes 3) Not enough information
