Answer:
a. The balls initial kinetic energy.
Explanation:
As we know that initially speed is given to the ball downwards so that it moved in a circle so then finally reached to point B
Now given that point B is higher than the initial position A from which it is projected
Now by energy conservation we know that
since final speed is zero so we have
so from above equation we can say that since initial kinetic energy is given to the ball so it will be able to reach the point which is higher than its initial position
so correct answer is
a. The balls initial kinetic energy.
Answer:
These forces are all equal and cancel each other out. Gravity pushes downward on the ice cream. This can also be called the weight of the ice cream. Buoyant force pushes the ice cream upward

Explanation:
it covers 20 metres in a second
Answer:
The value is 
Explanation:
From the question we are told that
The mass of the block is 
The force constant of the spring is 
The amplitude is 
The time consider is 
Generally the angular velocity of this block is mathematically represented as
=> 
=> 
Given that the block undergoes simple harmonic motion the velocity is mathematically represented as
=> 
=>
