A woman rides a carnival Ferris wheel at radius 17 m, completing 5.3 turns about its horizontal axis every minute. What are (a) the period of the motion, and the magnitude of her centripetal acceleration at (b) the highest point and (c) the lowest point? The position vector 7 = (4.30t)î + (et + ft²) locates a particle as a function of time t. Vector is in meters, t is in seconds, and factors e and fare constants. The figure gives the angle of the particle's direction of travel as a function of time (0 is measured from the positive direction of the x axis). What are (a) factor e and (b) factor f, including units? 20° 0° -20° 10 t(s) 20
