Solution :
Given :
Mass attached to the spring = 4 kg
Mass dropped = 6 kg
Force constant = 100 N/m
Initial amplitude = 2 m
Therefore,
a). 

= 10 m/s
Final velocity, v at equilibrium position, v = 5 m/s
Now, 
A' = amplitude = 1.4142 m
b). 
m' = 2m
Hence, 
c). 

Therefore, factor 
Thus, the energy will change half times as the result of the collision.

Answer:

Explanation:
To solve this problem we need to apply the concept related to Angular Acceleration. We can find it through the equation

Where for definition,

The number of revolution
was given by 20 times, then


We know as well that the salad rotates 6 more times, therefore in angle measurements that is

The cook at the end stop to spin, then using our first equation,

re-arrange to solve
,


We can know find the required time,

Re-arrange to find t, and considering that 



Therefore take for the salad spinner to come to rest is 3 seconds with acceleration of 
a person who alters their voice to make it seem as though the sound is coming from somewhere else, typically a puppet is a ventriloquist.
<h3>Which ventriloquist was the best?</h3>
Jimmy Nelson, an American ventriloquist who performed on television in the 1950s and 1960s, was born on December 15, 1928.
<h3>What makes it a ventriloquist?</h3>
The incorrect but long-held notion that the voice came from the stomach is explained by the word ventriloquism's Latin roots, ventri (belly) and loquor (to talk).
<h3>Why is a ventriloquist good?</h3>
Making your puppet seem lifelike and honing your voice are essential for becoming a competent ventriloquist. To divert attention from yourself, keep moving the body, arms, and head of the creature. To assist people forget that your puppet is actually you, try to make the character as different from you as you can.
