A bioengineer is interested in the energy requirements of athletes doing theshotput. From a videotape of a shotput throw, the bioengineer determines that the beginning of themotion is when the shot is stationary and is 1.50 m above the ground (height of the athlete’sshoulder when the shot is at the beginning of the throw). The shot has a mass of 7.25 kg. At theinstant the athlete’s hand releases the shot, it is 2.10 m above the ground. During the throw, theshot reaches a maximum height of 4.60 m above the ground and travels a horizontal distance of18.66 m from the point where it was released. How much work does the athlete do on the shotfrom the beginning of the motion to the instant of release?
