How much work does it take to raise a 14 kg  weight 4 m ?

May 17, 2018

Approximately $549$ joules.

Explanation:

Work done is given by the equation,

$W = F \cdot d$

where:

• $W$ is the work done in joules

• $F$ is the force exerted in newtons

• $d$ is the distance moved in meters

Here, the force is the weight's weight in newtons, which is $14 \setminus \text{kg"*9.8 \ "m/s"^2=137.2 \ "N}$.

Therefore, the work done is:

$W = 137.2 \setminus \text{N"*4 \ "m}$

$= 548.8 \setminus \text{J}$
