Problem 5: A wheel of radius R=.5m is rolling on a smooth horizontal surface. The wheel is initially rotating at a frequency of 1 revolution per second. At t=0, the wheel slows down with angular acceleration of a=-2t². The time t is in seconds and a is in rad/s². x=5.2t² Vo d = stopping distance a) Determine the frequency of revolution in Hertz (Hz). b) Determine the initial angular velocity (at t-0) of the wheel in rad/s. c) Find an expression the angular velocity (t) for t> 0. d) At what time does the wheel stop. e) Determine the angular displacement AO in radians for the wheel during stopping. f) Determine the horizontal stopping distance of the wheel (d) in meters. stops V=0
