A construction worker exerts 209N to move a load of bricks a distance of 10m across the parking lot,how much work does he do?
To calculate the work done by the construction worker, we use the formula: work = force × distance.
In this case, the force exerted by the construction worker is 209N and the distance the load of bricks is moved is 10m.
Therefore, the work done by the construction worker can be calculated as:
work = force × distance = 209N × 10m = 2090 N·m (or Joules).
So, the construction worker does 2090 Joules of work in moving the load of bricks across the parking lot.
