PHYS-1500 PHYSICAL MODELING FALL 2006 Still More of the Rocket in Orbit Program Below is a copy of the program for the rocket in orbit. This program will take a rocket from a low circular orbit to a higher orbit. Below the pictures of the spreadsheet are the contents of the cells. For the cells above the actual program, i.e. rows 1 through 11, only the contents of the cells containing formulae have been given. For rows 12 and 13, the contents of all cells have been given. When row 13 is complete, the entire row (except cell K13) should be copied to rows 14 through 513. Then, use the program to answer the questions on the assignment sheet.
