a weightlifter lifts a set of weights a vertical distance of 2.36. if a constant net force of 335 N is exerted on the weights how much net work is done on the weights?
(weight,newtons) x (distance lifted, meters) = (Work ,joules)
To calculate the net work done on the weights, you can use the formula:
Net Work = Force × Distance × cos(θ)
Where:
- Force is the magnitude of the net force applied on the weights (335 N in this case).
- Distance is the vertical distance over which the weights are lifted (2.36 m in this case).
- cos(θ) is the angle between the direction of the force and the direction of the displacement. Since the weights are lifted vertically, the angle between the force and displacement is 0 degrees, so cos(0) = 1.
Therefore, the net work done on the weights is:
Net Work = 335 N × 2.36 m × cos(0°) = 335 N × 2.36 m × 1 = 791.6 Joules
So, the net work done on the weights is 791.6 Joules.
