600 Joules of work is used to lift a box from the ground to a height of six meters. How much work would have been done if a lever would have been used with an effort arm of 12 meters and a load arm of 6 meters?(1 point) Responses 100 J 100 J 50 J 50 J 600 J 600 J 72 J
To calculate the work done using a lever, we can use the formula:
Effort arm × Effort = Load arm × Load
In this case, the effort arm is 12 meters, the effort is unknown, the load arm is 6 meters, and the load is 600 Joules. Plugging in these values, we get:
12 × Effort = 6 × 600
Simplifying, we have:
12 × Effort = 3600
Dividing both sides by 12, we find:
Effort = 300
Therefore, the work done using a lever would have been 300 Joules.
