Water flows steadily through a pipe of length L and radius R=75mm. The velocity distribution across the outlet is given by u=uma
x 1− r2 R2 and umax =3m=s. Evaluate the ratio of the x-direction momentum flux at the pipe outlet to that at the inlet.

Answer:
24.531 m
Explanation:
t = Time taken = 1.7 s
u = Initial velocity = 6.1 m/s
v = Final velocity
s = Displacement
g = Acceleration due to gravity = 9.81 m/s² = a
Equation of motion
The initial height of the rock above the ground is 24.531 m
