Question

a bullet hits the block kept on a horizontal frictionless surface and get embedded into it which of the following does not change change linear momentum , kinetic erg,temperature,gravationa
​

Answer 1

Gravitational potential energy of the block won't change

Explanation:

• The gravitation potential of the block remains the same as the height of the block also remains same along the process of hitting

• As the block is hit by a bullet when kept at rest the block acquire velocity by conservation of linear momentum.

• Hence, the linear momentum and kinetic energy changes.

• Also, kinetic energy of the bullet transforms into heat energy, the temperature of the box also changes
