# How much work would it take to push a  2 kg  weight up a  19 m  plane that is at an incline of  pi / 6 ?

180 j

#### Explanation:

There are multiple ways to do this

First Way;

Second way

we will use the formula method

The minimum force needed with neutralize the force of gravity pushing the block down the incline.

$\implies F = m g \cos \theta$

We know

$W = F \cdot s$

$W = m g \cos \theta \cdot s$

$W = 2 \cdot 10 \cdot \cos \left(\frac{\pi}{6}\right) \cdot 90 = 180 J$
