A crane lifts a load of logs 3 meters with a force of 5,200 Newtons. How much work did the crane do?
a. 150,000 J
b. 15,600 J
c. 150 J
d. 1560 J
The work done by the crane is calculated using the formula:
Work = Force x Distance
Given that the force is 5,200 Newtons and the distance is 3 meters, we can substitute these values into the formula:
Work = 5,200 N x 3 m = 15,600 J
Therefore, the crane did 15,600 Joules of work.
The correct answer is:
b. 15,600 J
