Ship rendezvous

Two ships, the S.S. Green and the S.S. Blue agree to rendezvous at sea.[br][br]Use the blue & green DOTS to set their initial positions.[br]Use the blue & green RINGS to set their speeds & headings.[br][br]Use the yellow dots to set the center of the rendevous region and its radius.[br][br]The yellow dot in the right hand panel will show the size of the separation of the ships as a function of time.[br][br]Write expressions for the positions of the two ships as functions of time.[br][br]How can you minimize the size of the rendezvous region while keeping it larger than some required minimum? [Keep in mind that a zero radius for the rendezvous region indicates a collision!]
