Solution

Slide 1 has a larger angle.

As slide 1 has a larger angle and steeper than slide 2, there will be more chances for the boy to get hurt while sliding on slide 1. Thus, slide 2 would be safer for the little boy than slide 1.

In a children's park, there is a slide which has a total length of 10 m and a height of St m (figure 8-E3). Vertical ladder are 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. (a) the work done by the boy on the ladder as he go: up, (b) the work done by the slide on the boy as he cornea down, (c) the work done by the ladder on the boy as he goes up. Neglect any work done by forces inside the body of the boy.

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 (figure 8-E3). 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. Find (a) the work done by the ladder on the boy as he goes up; (b) the work done by the slide on the boy as he comes down. Neglect any work done by forces inside the body of the boy.
