An exhausted bicyclist pedals somewhat erratically when exercising on a static bicycle. The angular velocity of the wheels follows the equation ω(t)=at−bsin(ct)fort≥0, where t represents time (measured in seconds), a = 0.500 rad/s2 , b = 0.250 rad/s and c = 2.00 rad/s .Part AThere is a spot of paint on the front wheel of the bicycle. Take the position of the spot at time t=0 to be at angle θ=0 radians with respect to an axis parallel to the ground (and perpendicular to the axis of rotation of the tire) and measure positive angles in the direction of the wheel's rotation. What angular displacement θ has the spot of paint undergone between time 0 and 2 seconds?Part BExpress the angular displacement undergone by the spot of paint at t=2 seconds in degrees. Remember to use the unrounded value from Part A, should you need it. Express your answer in degrees using three significant figures. Part CWhat distance d has the spot of paint moved in 2 seconds if the radius of the wheel is 50 centimeters?Part DWhich one of the following statements describes the motion of the spot of paint at t=2.0 seconds?Which one of the following statements describes the motion of the spot of paint at seconds?A)The angular acceleration of the spot of paint is constant and the magnitude of the angular speed is decreasing. B) The angular acceleration of the spot of paint is constant and the magnitude of the angular speed is increasing. C) The angular acceleration of the spot of paint is positive and the magnitude of the angular speed is decreasing. D) The angular acceleration of the spot of paint is positive and the magnitude of the angular speed is increasing. E) The angular acceleration of the spot of paint is negative and the magnitude of the angular speed is decreasing. F) The angular acceleration of the spot of paint is negative and the magnitude of the angular speed is increasing.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
