# How much work does it take to raise a 33 kg  weight 94 m ?

Mar 1, 2016

$30 \text{kJ}$

#### Explanation:

The force required to overcome the weight of a $33 \text{kg}$ object is

$F = m g$

$= \left(33 {\text{kg") * (9.8 "m/s}}^{2}\right)$

$= 323.4 \text{N}$

The work done to lift such an object up by $94 \text{m}$ is the force exerted multiplied by the distance raised.

$W = F \cdot d$

$= \left(323.4 \text{N") * (94 "m}\right)$

$= 30400 \text{J}$
