The tractor exerts a towing force T$=400$lb$.$ It has a weight of $8800$ lb and a

center of gravity located at G$\_($T$).$ An additional weight of $600$ lb is added to its

front having a center of gravity at G$\_($A$).$ Take mu$\_($s$)=0\mathrm{.}4.$ The front wheels are free to

roll. $($Eigure $1)$
