Answer:
W = 200 J
Explanation:
Work will be equal to the change in kinetic energy
W = ½mv² - 0
W = ½(0.010)200²
W = 200 J
Answer:
The time taken is 
Explanation:
From the question we are told that
The mass of the ball is 
The time taken to make the first complete revolution is t= 3.60 s
The displacement of the first complete revolution is 
Generally the displacement for one complete revolution is mathematically represented as

Now given that the stone started from rest 


Now the displacement for two complete revolution is


Generally the displacement for two complete revolution is mathematically represented as

=> 
=> 
So
The time taken to complete the next oscillation is mathematically evaluated as

substituting values


True, I just learned this a week ago. Is this for Chemistry?
