A group of athletes were tested for isometric endurance by measuring the length of time they could resist a load pulling on their legs while seated. The approximate amount of time (called the holding time) that they could resist the load was given by the formula t=31,293w^-2.5,where w is the weight of the load in pounds and the holding time t is measured in seconds. a. Determine the holding time for a load of 32lb. b.When the weight of the load doubled, by what factor is the holding time changed?
