Mary Anne Sorensen's airplane crashed on a mountain in the Yukon wilderness. Sorensen weighed 150. pounds at the time of the crash and 110. pounds when she was rescued 50.0 days later. Assuming that death occurs when 50.0% of her body weight is lost, estimate Sorensen's survival time, assuming
a. A constant weight-loss rate.
b. An exponential weight loss-time relation of the form w = woexp(-αt), where α is a constant and wo is her weight at the time of the crash.
net displacement of an object equal to zero
A gas water heater burns natural gas. Each gram of natural gas burned yields approximately 13,000 calories of energy. A typical water heater takes in water at about 20oC (68oF) and raises its temperature to 60oC (140oF). A typical “low-flow” showe..
