To understand rigid-body rotation about a translating axis. An exhausted bicyclist pedals somewhat erratically. The angular velocity of the front tire, as measured with respect to an axis fixed at the tire’s center, is given by ω(t)=12t−14sin(2t) for t≥0 where t represents the time in seconds and ω(t) is measured in radians per second. Assume that the tires roll without slipping The bicycle’s front tire has a spot of paint on it. Take the spot’s position at time t=0.00s to be at angle θ=0.00 radians with respect to an axis parallel to the ground (and perpendicular to the axis fixed at the tire’s center) and take angles in the direction of the tire's rotation to be positive. What angular displacement θ(2) has the spot undergone between 0.00 and 2.0 s? If the tire’s radius is 23 cm, what is d, the magnitude of the spot’s displacement after 2.0 seconds? Which one of the following statements describes the spot’s motion at t=2.0s? The wheel’s angular acceleration is constant and the…

The velocity of a particle changes from -8 fps to 58 fps during a 10-sec intervalduring which its acceleration increases uniformly with the time from an initial valueof 3 fps2. Determine the displacement covered in the 10-sec interval. Draw the v-tand s-t curves.
The 100 meter diameter wheel needs to be designed so that it rotates at a constant rate and every complete revolution takes 15 minutes. The wheel has been installed in a vertical plane and the lowest seat is 2m above the ground surface. Each ride consists of only one full rotation. Find a further general expression for the horizontal displacement of the rider from its initial position with respect to both time and angle of rotation and hence determine the speed of the rider when t= 180 sec. Using calculus, determine what the maximum horizontal and vertical speeds of the rider would be and at which points during the ride they occur. State expressions for the acceleration of the rider in both horizontal and vertical directions and show that the resultant acceleration experienced by the rider is independent of where on the ride he/she might be. In designing a new wheel with the same diameter and same ride duration as before it is proposed that the wheel’s angular speed should not…
