At an amusement park, a swimmer uses a water slide to enter the main pool If the swimmer start at rest slides without friction and descend through a vertical height of 2.31m what is her speed at the bottom of the slide

v = 6.72 m/s

Explanation:

Given that,

Vertical height, h = 2.31 m

We need to find the speed at the bottom of the slide. Let the speed be v. We can find it using the conservation of energy such that,

Put all the values,

So, her speed at the bottom of the slide is equal to 6.72 m/s.

according to jean piaget, in what stage of cognitive development are children able to understand conservation task?
