Question: The 7 5 - l b uniform rectangular plate is initially at rest on the smooth horizontal surface in the x - y plane in

The

75 - l b

uniform rectangular plate is initially at rest on the smooth horizontal surface in the

x - y

plane in the position shown. Two forces are applied to two corners of the plate, as shown. If

P = 30 l b, = 60, b = 2 f t,

and

c = 1.4 f t,

determine the angular acceleration of the plate, the magnitude of the acceleration of the center of mass, and the magnitude of the initial acceleration of corner

A .

The 7 5 - l b uniform rectangular plate is
