Answer:
T = 23.92 m
Explanation:
given,
mass of the diver = 50.9 Kg
Resistant force from the water = f = 1492 N
diver come top rest under water at a distance = 6 m
acceleration due to gravity = 9.81 m/s²
final velocity = v = 0 m/s
initial velocity = u = ?
total distance = ?
Now acceleration of body under water
f = m a
using equation of motion
v² = u² + 2 a s
0 = u² - 2 x 29.31 x 6
u = 18.75 m/s
now.
calculating distance of the diver in air
v² = u² + 2 a s
0 = 18.75² - 2 x 9.81 x s
s = 17.92 m
total distance
T = 17.92 + 6
T = 23.92 m
the total distance between the diving board and the diver’s stopping point underwater T = 23.92 m
