Question

1 a piano with a weight of 11,000 newtons needs to be moved from the 1st floor of a building. the distance from the 1st floor to the 3rd floor is 8 meters. how much work is done lifting the piano?

Explanation:

Step1: Recall work formula

Work $W$ equals force $F$ times distance $d$, so $W = F \times d$.

Step2: Substitute given values

The weight is the force $F=11000\ \text{N}$, distance $d=8\ \text{m}$.
$W = 11000 \times 8$

Step3: Calculate the product

$W = 88000$

Answer:

88000 joules
