1. The problem statement, all variables and given/known data How much force is exerted when an individual leg presses 68 kg twelve times in 24 seconds? The leg press machine is a horizontal press machine. Distance pressed forward 14 inches 2 seconds forward followed by 2 seconds reversed for each rep was held constant through all twelve repetitions. Second question: If a 100 kg individual with a 28 inch stride length and runs with a hip flexion of 45 degrees and these values are held constant, runs .11 miles in a straight line in 26 seconds, how much force was exerted by this individual? Are the two forces the same? Could the running individual use the force from running and convert it to a value that could be used to weight train (force in pounds or kg?)? If not what are the appropriate equations to find out what I am trying to find? Is there variables that I am missing? Thanks for any help. Chris H.
