P 1 = 101,325 Pa (atmospheric pressure)
Milk has almost same density as water: (Rho)= 1,000 kg /m³
P 2 = 101,325 Pa + 1,000 kg/m³ · 9.81 m/s² · 0.1 m = 102,306 Pa
The hydrostatic equation:
P 1 + (Rho)v1² / 2 = P 2 + (Rho)·g·h2
101,325 + 1,000 v1²/2 = 102,306 + 1000 · 9.81 · 0.1
500 v 1² = 102,306 + 981 - 101,325
v 1² = 3.924
v 1 = √ 3.924
v 1 = 1.98 m/s
The initial velocity of outflow is 1.98 m/s.

Explanation:
Hi!
In a (x, y) coordinate representation, the two forces are:
The sum of the two forces is:
The angle to x-axis is calculated using arctan:
The magnitude is:
The angular velcoity of this cylinder when the downward speed of the elevator is 1.2 m/s would be 6 rad/s.
<u>Given the following data:</u>
Radius of cylinder = 0.20 meter.
Linear velocity = 1.2 m/s.
<h3>What is angular velocity?</h3>
Angular velocity can be defined as the rate of change of angular displacement of an object with respect to time. Thus, it is a measure of how fast and quickly an object revolves or rotates relative to another point or how its angular position changes with respect to time.
<h3>The formula for angular velcoity.</h3>
Mathematically, angular velcoity is given by this formula:
Substituting the given parameters into the formula, we have;
Angular velocity = 6 rad/s.
