Two forces act on a $55-kg$ object. One force has magnitude $65$ N directed $59$ clockwise from the positive $x$ axis, and the other has a magnitude $35$ N at $32$ clockwise from the positive $y-$axis. What is the magnitude of this object's acceleration?

A series of weights connected by very light cords are given an upward acceleration of $4\mathrm{.}00\frac{m}{s}2$ by a pull $P,$ as shown in the figure. $A,B,$ and $C$ are the tensions in the connecting cords. The SMALLEST of the three tensions, $A,B,$ and $C,$ is closest to
