Calculate the work done in lifting a 600-N barbell 1.6m above the floor.
Express your answer to two significant figures and include the appropriate units.
600 * 9.81 * 1.6 Joules
2,207.0J
To calculate the work done in lifting the barbell, we can use the formula:
Work = Force × Distance
In this case, the force is the weight of the barbell, which is given as 600 N, and the distance is the height above the floor, which is given as 1.6 m.
So, to calculate the work done, we substitute the given values into the formula:
Work = 600 N × 1.6 m
Using a calculator, we find:
Work = 960 Joules
Therefore, the work done in lifting the 600-N barbell 1.6 m above the floor is 960 Joules.
