3 Problem Two UNCC engineering students skipped class last Thursday to go to Carowinds amusement park. Student A decides to ride the Carolina Cyclone while the Student B goes on the Scream Weaver. At the instant shown, the Scream Weaver is completely vertical and its kinematics are well approximated by a disk with radius R = 23 m spinning around point O at a rate=307/180 rad/s in the clockwise direction. Student B is located at angular position 0 = 45 deg. At this same instant, Student A is barrelling down a flat segment of the track moving at a speed of VA = 17 m/s and decelerating at aA = -1.5 m/s². Ω 0 B R A a A VA What is the velocity and acceleration of student A as observed by student B? State your an- swer symbolically in terms of (v₁, R, N, 0, ₁) and the unit vectors of an inertial frame I = {0,11,12,13}, then evaluate this vector with the data provided. (Hint: Use a polar frame centered on O to determine VB/O and aB/o in terms of ê, and êe, which can then be expressed in the inertial frame (also at O) with unit vectors 11 and 12.)
