A bullet penetrates a wooden block and loses its velocity by a half. What is the ratio between
the initial kinetic energy of the bullet and kinetic energy when the bullet leaves the block?
Answers
Answer:
4:1
Explanation:
Maybe just simply kinetic energies k ratio daal do since mass to change krega nhi aur final velocity u/2 (if u is initial velocity).
Answer:
Explanation:
We must exert force on an object to accelerate it. We have to put up the effort to use force. Energy is transmitted when work is done on an object, and the thing then moves at a new, constant speed. The energy that is transported is referred to as kinetic energy, and it is influenced by the mass and speed attained.
The amount of labour an object can accomplish through motion is measured by its kinetic energy.
Given:
Bullet breaks through the block and loses half of its speed.
Aim:
ratio between the bullet's initial kinetic energy and its final kinetic energy when it departs the block.
Let V represent the bullet's starting speed.
Initial Kinetic energy
Final velocity of the bullet
Final kinetic energy
Ratio
