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.
