In a children's park , there is a slide which has a total length of 10m and a height of 8m. Vertical ladder are provided to reach the top. A boy weighing 20ON climbs up the ladder to the top of the slide and slides down to the ground. The average friction offered by the slide is 3/ 10 of his weight . Find a) Work done by the boy on the ladder as he goes up. b) Work done by the slide on the boy as he comes down. () Work done by the laddes on the boy as he goes up Neglect any work done by forces inside the body of the boy
