1) the image shown a group of cyclist racing on a velodrome. What kind of rigid body motion applied into the activity? a) Curvilinear translation b) Rectilinear translation c) Rotation about fixed axis d) General plane motion 2) The angular velocity 𝜔 of a rigid body in planar motion: a) Dependson the distance from rotation axis b) is the same for all points on the body c) Varies with the direction of motion. d) Is zero if the body is in pure translation. 3) A rigid body is in pure rotational motion about a fixed axis. Which of the following statements is true? a) All points on the body have the same linear velocity b) Linear acceleration is zero for all points c) Linear velocity is proportional to the radial distance from the axis of rotation d) Angular velocity ω varies with time 4) In general plane motion of a rigid body, the motion can be described as a combination of: a) Pure translation and pure rotation about a fixed point b) Pure rotation about the center of mass and pure translation of the center of mass c) Pure rotation about an instantaneous center of zero velocity and pure translation of a reference point d) Pure rotation about the instantaneous center of zero velocity and translation of the center of mass 5) In pure rotational motion, the angular acceleration α: a) Is constant for all points on the body if the rotation is uniform. b) Is proportional to the radial distance from the axis of rotation c) Depends on the moment of inertia of the body d) Is the same for all points on the body.
