Q. In a children's park, there is a slide which has a total length of $10\, m$ and a height of $8.0 \,m$. A vertical ladder is provided to reach the top. A boy weighing $200\, N$ climbs up the ladder to the top of the slide and slides down to the ground. The average friction offered by the slide is three-tenth of his weight.

Work, Energy and Power

Solution:

Force, $F=\frac{3}{10} m g$
As, $W=-F s$
or $W=-\frac{3}{10} m g s$
or $W=-\frac{3}{10} \times 200 \times 10\, J =-600\, J$
