Muhammad lifts. an 8.0kg piece of timber a distance of 5.0m How muck work is he doing?

(use 10 m/s for gravity)

1 answer

To calculate the work done by Muhammad, we can use the formula:

Work = Force × Distance

The force exerted on the timber can be calculated using the weight formula:

Force = Mass × Gravity

where the mass is 8.0kg and gravity is 10 m/s².

Force = 8.0kg × 10 m/s² = 80 N

Now we can substitute the force and distance into the work formula:

Work = Force × Distance
Work = 80N × 5.0m = 400 Joules

Therefore, Muhammad is doing 400 Joules of work.
