What percentage of kinetic energy of a moving particle is transferred to a stationary particle it strikes when the stationary particle has a mass (a) 19 times (b) equal to (c) 1/19 times the mass of the moving particle ?

Explanation

To solve the problem of how much kinetic energy is transferred from a moving particle to a stationary particle during a collision, we will analyze three different scenarios based on the mass of the stationary particle relative to the moving particle.

### Given:
- Mass of moving particle = \( m \)
- Velocity of moving particle = \( v \)
- Mass of stationary particle = \( k \cdot m \) (where \( k \) varies)
