SUMMARY
The net work done on weights lifted vertically is calculated using the formula W = F · d, where W represents work, F is the net force, and d is the distance. In this case, a weight lifter exerts a constant net force of 394 N over a vertical distance of 3.64 m. Therefore, the net work done on the weights is 394 N multiplied by 3.64 m, resulting in a total of 1,433.76 Joules.
