- A weight lifter lifts a 380-N set of weights from ground level to a position over his head, a vertical distance of 2.40 m. How much work does the weight lifter do, assuming he moves the weights at constant speed? My answer was 855 This was my feedback Please fix this Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. J2.
