MATH 115 Chapter Notes - Chapter 5: Montgolfier Brothers
Document Summary
The montgolfier brothers (joseph and etienne) were eighteenth-century pioneers in the field of hot-air ballooning. Had they had the appropriate instruments, they might have left us a record, like that shown in figure 5. 75, of one of their early experiments. Given this, the acceleration is positive when the slope is positive, and negative when it is negative. In this case, acceleration is positive from 0 t < approximately 42, or between t=0 minutes and t 42 minutes. Which is shown in the graph below. minutes. The height of the hill above the starting point is given by . 0 approximately 430 feet - approximately 240 feet = approximatly 190 feet.
