Answer:
1. 
2.
3. 
4. 
Explanation:
1. The frequency of rotation is given by:

Where:
ω: is the angular speed = 50 rotations (revolutions) in 25 s.
We need to convert the units of ω.

Now, the frequency is:

2. The frequency is:
We know:
5 laps = 5 revolutions
t: time = 450 s
3. The frequency of the pendulum is:

4. We have:
θ: number of revolutions = 48 rev
f = 12 Hz
t =?
The time can be calculated as follows:

It really doesn't matter whether the two masses are joined by a light string, a light reinforced concrete and steel frame, a light coating of strong glue, or a layer of scotch tape that's one atom thick. They look like a single mass of 10 kg.
<u>Part a). </u>Force = (mass) x (acceleration)
The acceleration of 10 kg of mass pulled with 100N of force is
100 N = (10 kg) x (acceleration)
Divide each side by (10 kg):
Acceleration = (100 N) / (10 kg)
<em>Acceleration = 10 m/s²</em>
<u>Part b).</u> Now look at just the rear 16 kg. It stays hooked onto the front 4 kg, and everything moves together. So both pieces must have the same distance, velocity, acceleration etc. We know that the acceleration is 10 m/s² .
Force = (mass) x (acceleration)
Force on the rear 16 kg = (16 kg) x (10 m/s²)
<em>Force = 160 Newtons</em>

Answer:
A capon (from Latin: caponem) is a cockerel (rooster) that has been castrated or neutered, either physically or chemically, to improve the quality of its flesh for food, and, in some countries like Spain, fattened by forced feeding.
