4T -rk -rt Part (e) Enter an expression for the velocity function, vr, associated with the position function you entered in part (a), in terms of r, w, and t. Expression : Vx = 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(o), sin(0), a, o, 0, g, m, r, t Part (f) For an angular speed of w = 2.1 rad/s, find the value of vr, in meters per second, at time t = 0.22 s. Numeric : Anumeric value is expected and not an expression. Vx = Part (g) How is the velocity you entered in part (e) related to the tangential velocity of the particle undergoing uniform circular motion in the problem statement? MultipleChoice : 1) There is no relation between them. 2) The velocity v, is the x-component of the tangential velocity. 3) v, is equivalent to w. 4) They are the same. 5) There is not enough information. Part (h) Enter an expression for the acceleration function, a,, associated with the position function you entered in part (a), in terms of r, w, and t. Expression : ax = 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(o), sin(0), a, o, 0, g, m, r, t Part (i) For an angular speed of w = 2.1 rad/s, find the value of a, in meters per second squared, at time t 0.22 s. Numeric : A numeric value is expected and not an expression. ax =
