What do you mean by 'split the kinetic energy'?ashvinthecha said:I found the kinetic energy of the first ball, then split the knietic energy between the two balls after the collision to individually find the velocity of each.

Hint: What else is conserved during the collision besides energy?
You cannot assume that the kinetic energy divides equally.ashvinthecha said:I divided the total kinetic energy by two...
Yes. Use conservation of momentum and energy to solve for the final speeds.and is momentum the answer to your question

Write equations for energy conservation and momentum conservation, then solve them.ashvinthecha said:How do I do that?
Kinetic energy is the energy an object possesses due to its motion. It is a scalar quantity that depends on both the mass and velocity of the object.
Kinetic energy is calculated using the formula KE = 1/2 * m * v^2, where m is the mass of the object and v is its velocity. The unit for kinetic energy is joules (J).
According to the law of conservation of energy, energy cannot be created or destroyed, but it can be converted from one form to another. In the case of kinetic energy, it can be converted into other forms of energy, such as potential energy, but the total amount of energy remains constant.
Kinetic energy is directly proportional to an object's mass and the square of its velocity. This means that the greater an object's mass and velocity, the more kinetic energy it possesses. In terms of motion, the higher an object's kinetic energy, the faster it will be moving.
Some examples of kinetic energy in everyday life include a moving car, a thrown ball, a swinging pendulum, and a running person. Essentially, any object that is in motion possesses kinetic energy.
