# How much work does it take to raise a 24 kg  weight 8 m ?

Apr 6, 2018

$\implies W = 1920 \text{ J}$

#### Explanation:

Work is simply force applied for some distance.

In this case, we are moving $24 \text{ kg}$ vertically agains gravity, so we need to overcome the weight of the object. Assuming the gravitational acceleration is $10 {\text{ ms}}^{-} 2$.

$F = m g = 24 \left(10\right) = 240 \text{ N}$

The distance moved is $8 \text{ m}$. The work done is therefore:

$W = F x = 240 \left(8\right) = 1920 \text{ J}$
