Answer:
The fraction of the total initial kinetic energy is lost during the collision is
Explanation:
Given that,
Mass of one piece = 300 g
Speed of one piece = 1 m/s
Mass of other piece = 600 g
Speed of other piece = 0.75 m/s
We need to calculate the final velocity
Using conservation of energy
Put the value intro the formula
We need to calculate the total initial kinetic energy
Using formula of kinetic energy
Put the value into the formula
We need to calculate the total final kinetic energy
Using formula of kinetic energy
Put the value into the formula
We need to calculate the energy lost during the collision
Using formula of energy lost
Hence, The fraction of the total initial kinetic energy is lost during the collision is
