Homework Statement
A weight lifter lifts a set of 390 N weights from ground level to a position over his head, a vertical distance of 1.75m. How much work does the weight lifter do, assuming he moves the weights at a constant speed?
I am not confident in my physics skills so I am really looking for someone to grade my work and give me feedback; thanks!
