Answer:
10.85 m/s
Explanation:
m = 1200 kg, h1 = 19 m, h2 = 13 m
Let v be the velocity
Use the conservation of energy
Potential energy at 19 m = Potential energy at 13 m + kinetic energy
m x g x h1 = m x g x h2 + 1/2 mv^2
m x g (h1 - h2) = 0.5 x m v^2
g (h1 - h2) = 0.5 v^2
9.8 (19 - 13) = 0.5 x v^2
v = 10.85 m/s

= 15 ml
Since the water rises 15 ml in the graduated cylinder, its volume is 15 ml^3

Calculate the length of a spaceship as follows:
l = l₀√1 - v²/c²
=(400 m)√1 - (0.75c)2 c²
=264.575m.
