The angular velocity of the propeller is 136.1 rad/s; linear velocity is 153.1 m/s; centripetal acceleration 20835.2 m/s² and 2123.8 g.
<h3>What is the angular velocity of the propeller?</h3>
The angular velocity of the propeller in rad/s is given as follows:
1300 rev/min = 1300 * 2π/60 = 136.1 rad/s.
b. The linear velocity, v = radius * angular velocity
Linear velocity, v = 2.25/2 * 136.1
v = 153.1 m/s
c. Centripetal acceleration,
Centripetal acceleration in terms of g;
Therefore, the angular velocity of the propeller is 136.1 rad/s; linear velocity is 153.1 m/s; centripetal acceleration 20835.2 m/s² and 2123.8 g.

Answer:
a
Generally from third equation of motion we have that
Here v is the final speed of the car
u is the initial speed of the car which is zero
is the initial position of the car which is certain height H
is the final position of the car which is zero meters (i.e the ground)
a is the acceleration due to gravity which is g
So
=>
b

Answer:
Measuring cup and graduated cylinder
Explanation:
These tools measure the volume of liquid matter. Measuring cups are used frequently in cooking and provide measurements generally in ounces and grams. A graduated cylinder is used in laboratories and in research and allows for a greater degree of precision in measuring the volume.
Answer:
The three balls would hit the ground at the same time.
Explanation:
As Galileo Galilei proved with an experiment in which he put in free fall different objects of different mass, but the same shape, all objects fall with the same acceleration when are allowed to free falling. So, if the initial conditions were the same (height, initial velocity, and time), the three balls would hit the ground at the same time, no matter which material they are made of.
