# A Person is Painting the Walls of His House. He Stands on a Ladder with a Bucket Containing Paint in One Hand and a Brush in the Other. Suddenly the Bucket Slips from His Hand and Falls to the Floor. - Physics

Sum

A person is painting the walls of his house. He stands on a ladder with a bucket containing paint in one hand and a brush in the other. Suddenly the bucket slips from his hand and falls to the floor. If the bucket with the paint had a mass of 6 kg and was at a height of 2 m at the time it slipped, how much gravitational potential energy was lost together with the paint?

#### Solution

Given:

$\text{ Mass of the bucket with the paint, m = 6 kg }$

$\text{ Height at which the bucket is placed, h = 2 m }$

$\text{ Potential energy of the bucket with the paint at the given height, }$

$\text{ P . E . = mgh }$

$= 6 \times \left( 9 . 8 \right) \times 2$

$= 117 . 6 J$

$\text{ P . E . on the floor } = 0$

$\text{ Loss in potential energy } = 117 . 6 - 0$

$= 117 . 6 J \approx 118 J$

Is there an error in this question or solution?
