A weightlifter lifts a weight of 500N from the ground over her head, a distance of 1.8m. How much work has been done to move the weight?
Remember that the work formula is force*distance. So you would multiply 500*1.8 to get 900 newton-meters of work.
it will be 900n
To calculate the work done to move the weight, you can use the formula:
Work = Force × Distance
In this case, the force is given as 500 Newtons (N), and the distance is given as 1.8 meters (m).
So, the work done to move the weight can be calculated as:
Work = 500 N × 1.8 m
Now we can calculate the work:
Work = 900 N·m
Therefore, the work done to move the weight is 900 Newton-meters (N·m).
To find the amount of work done to move the weight, we can use the formula: work = force × distance.
In this case, the force is given as 500N, and the distance is 1.8m.
So, to calculate the work done, we simply multiply the force by the distance:
work = 500N × 1.8m
= 900 Joules
Therefore, the work done to move the weight is 900 Joules.
