I am going to say
C. Energy contained in the nucleus of an atom
Answer:
m = 2218.67 kg
Explanation:
It is given that,
Initial velocity, u = 7.5 m/s
Final speed of an object, v = 0 (at rest)
Force, F = 5.2 kN
Time, t = 3.2 s
We need to find the mass of the object. Force acting on an object is given by :
F = ma
m is mass, a is acceleration

So, the mass of the object is 2218.67 kg
Because it occurs frequently and its does not cause as much damage as boloni
Answer:


Explanation:
Given

To start with, we begin with

Substitute the expression for F


Acceleration (a) is:

So, the expression becomes:

-----------------------------------------------------------------------------------------
Velocity (v) is:
--- distance/time



--------------------------------------------------------------------------------------------
So, we have:


Divide both sides by 


Divide both sides by m


Integrate:






Next, is to get the maximum velocity by distance x.
To do this, we find the derivation by x





Divide both sides by 

Take cube roots of both sides
