The Object if mass m$1=1kg$ and m$2=4kg$ are connected to each other as in the figure with a rope whose weight is neglected. The kinetic friction coefficient is known to be $0\mathrm{.}5$ between the object of mass $4$ kg and the surface, Note: Take $=53,$ g$=9\mathrm{.}8$

a$)$ Draw the frec body diagen of the Gediles of $m1$ and $m.(10$ p $)$

b$)$ Find the magnitude of the tension force in the rope connecting the objects. $(10$ p$)$
