Question

How do you find the final velocity of two objects colliding when you only have the mass and initial velocity of both objects

Answer 1

Answer:

We are required to analyze the conservation of kinetic energy in a perfectly inelastic collision.

kinetic energy:K=1/2mv²

momentum:p=mv

Explanation:

Using the equations for final velocity in terms of masses and initial velocity for a perfectly inelastic collision, work out the final kinetic energy. Calculate the initial kinetic energy and show that kinetic energy is not conserved. Use variables, no numbers

Answer 2

You need to follow law of conservation of energy

• Energy is neither created nor destroyed

We know

• Kinetic Energy=mass(Velocity)^2

You may use momentum formula mass×velocity

In both you need to form equations then solve for final velocity
