Answer:
The fountain is 3.43 m high.
Explanation:
Circumference of the pool = 15 m.
C = 2r
where C is the circumference and r its radius.
r =
=
r = 2.3864
radius of the pool = 2.40 m
So that the height of the fountain, h, can be determined by applying trigonometric function.
Tan θ =
Tan 55 =
h = Tan 55 x 2.4
= 1.4282 x 2.4
= 3.4277
h = 3.43 m
The height of the fountain is 3.43 m.
We use kinematic equation,
Here, h is vertical height, u is initial vertical velocity, t is time taken and g is acceleration due to gravity.
As diver dives out horizontally, his velocity is directed horizontally; that is, the initial vertical velocity is 0. So above equation becomes
Given, t =3 s.
Therefore,
.
Now the horizontal distance of the diver to hit the water from base,
