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
