A driver starts his car with the door on the passenger's side wide open $(\theta=0) .$ The 100 -lb door has a centroidal radius of gyration $\bar{k}=12$ in. and its mass center is located at a distance $r=20$ in. from its vertical axis of rotation. Knowing that the driver maintains a constant acceleration of $4 \mathrm{ft} / \mathrm{s}^{2},$ determine the angular velocity of the door as it slams shut $\left(\theta=90^{\circ}\right)$

In physics, kinematics is the description of the motion of objects and systems in the frame of reference defined by the observer. An observer has to be specified, otherwise the term is meaningless.

In mathematics, a position is a point in space. The concept is abstracted from physical space, in which a position is a location given by the coordinates of a point. In physics, the term is used to describe a family of quantities which describe the configuration of a physical system in a given state. The term is also used to describe the set of possible configurations of a system.
