The answer is Gravity

There's always a gravity between any 2 objects in this universe. between you and your computer, between you and the floor, between your chair and your table, etc.

We just dont feel it because we live in earth which negates all of those gravities with its own.

At the local swimming pool, the diving board is elevated h = 8.5 m above the pool surface and overhangs the pool edge by L = 2 m
Tasya [4]

Answer:

Part a)

t_w = \sqrt{\frac{2h}{g}}

Part b)

t_w = 1.32 s

Part c)

d_w = 6.88 m

Explanation:

Part a)

As we know that the diver will have zero velocity in vertical direction

so here we can say that

\Delta y = v_y t + \frac{1}{2}a_y t^2

h = \frac{1}{2}gt^2

t_w = \sqrt{\frac{2h}{g}}

Part b)

as we know that

h = 8.5 m

g = 9.81 m/s^2

so we will have

t_w = \sqrt{\frac{2(8.5)}{9.81}}

t_w = 1.32 s

Part c)

Distance covered by diver from the edge of the pool is given as

d_w = L + v_w t_w

d_w = 2 + (3.7)(1.32)

d_w = 6.88 m
