Two pieces of clay are moving directly toward each other. when they collide, they stick together and move as one piece. one piece having mass 300 g is moving to the right at a speed of 1 m/s. the other piece has mass 600 g and is moving to the left at a speed of 0.75 m/s. what fraction of the total initial kinetic energy is lost during the collision?

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

6/12=1/2

step-by-step explanation:

reserve is the answer
