Question

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

Answer 1

v = 6.72 m/s

Step-by-step 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,

`(1)/(2)mv^2=mgh\\\\v=√(2gh)`

Put all the values,

`v=√(2* 9.8* 2.31) \\\\v=6.72\ m/s`

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