What was the initial kinetic energy of the small mass before the collision?
What is the kinetic energy of the two-mass combination after the collision?
To calculate the initial kinetic energy of the small mass before the collision, you need to know the mass of the small mass and its initial velocity. The equation for kinetic energy is K = 1/2 * m * v^2, where K is the kinetic energy, m is the mass, and v is the velocity.
To find the kinetic energy of the two-mass combination after the collision, you need to know the total mass of the two masses together and their final velocity. Again, you can use the same equation for kinetic energy to calculate it.
To answer both questions accurately, you would need more specific information such as the mass and initial velocity of the small mass, as well as the total mass and final velocity of the two-mass combination after the collision.
