A construction worker is using his weight to keep a stationary stack of wooden beams from falling. If the construction worker uses 689.0 N of force to hold 10 beams stationary against a wall, how much work does he do? (1 point)
0 J
0.0150 J
68.9 J
6,890 J
is it a. someone help me
It could either be A or D...
I would say it is 0 because work is the a function of Force and horizontal displacement.
Soooo...…………...Whats is it?!
ms sue pls help
It is a.
To calculate the work done by the construction worker, we can use the formula:
Work = Force x Distance
The question states that the construction worker is using a force of 689.0 N to keep the stack of wooden beams stationary against a wall. However, no information about the distance is given.
Since the distance is not specified, we can assume that the displacement of the wooden beams is zero since they are stationary. In this case, work is defined as the product of force and displacement, and since the displacement is zero, the work done will also be zero.
Therefore, the correct answer is option A) 0 J, as the construction worker does not perform any work in this situation.
