Answer:
The answer is
Explanation:
If the ball is thrown vertically, the equation of its position is
So setting our coordinate system in the position of throwing , the equation for A is
and for B
where
due to the delay of the throwing between A and B, "t"
.
Now, the balls passing each other means that
then
cancelling some terms...
so
The total kinetic energy of cylinder at that instant is (1/2)mv² where m is the mass of the cylinder.
Kinetic energy is actually acquired by the body when it is travelling with some speed. In this universe energy never creates never destroy, it actually converts from one form to another.
Kinetic energy has various types like:
- Rotational kinetic energy
- Radiant kinetic energy
- Thermal kinetic energy
- Sound kinetic energy
- Electrical kinetic energy.
When any body is holding any particular height, in that case it has potential energy.
There are various theorems which are actually derived from the kinetic energy. One of them is work energy theorem.
We know very well that formula of kinetic energy is (1/2)mv²
Hence, is (1/2)mv².
