To calculate the amount of work, we can use the equation:
W = F x d
where W is the amount of work (in joules), F is the force (in newtons), and d is the distance (in meters).
In this case, the person applies a force of 10 N to lift the box over a distance of 3 m. So, we can substitute these values into the equation and solve for W:
W = 10 N x 3 m
W = 30 joules
Therefore, the amount of work done to lift the box is 30 joules.
Imagine a person using a lever applies a force of 10 Newtons to lift a box over a distance of 3 meters. Use the equation W = F x d to calculate the amount of work that is done.
