Question

A weightlifter lifts barbells of 200 newtons above his head to a height of 2 meters. How much work does he do? W = F x d

Answer 1

400Nm

Explanation:

Work is said to be done when a force applied to an object causes the object to move thriugh a distance.

Work done = Force × distance moved in the direction of the force

Given force = 200N

Distance = 2m

Work done = 200 × 2

Works done = 400Nm

Answer 2

For this case we have that the work is given in units of Joules.

`W = F * d`

Where:

W: It's the job

F: It is the force

d: It is the distance

According to the data we have:

`W = 200 * 2\\W = 400`

Thus, the work done by the weightlifter is 400J

Answer:

The work done by the weightlifter is 400J
