Question

Expression for final velocity after elastic collision

Answer 1

An inelastic collision is any collision between objects in which some energy is lost. A special case of this is sometimes called the "perfectly" inelastic collision. In a perfectly inelastic collision, two objects collide and stick together. The momentum of the objects before the collision is conserved, but the total energy is not conserved. The final velocity of the combined objects depends on the masses and velocities of the two objects that collided. The units for the initial and final velocities are m/s, and the unit for mass is kg.





 mass of a first object (kg)

 mass of a second object (kg)

 initial velocity of the first object (m/s)

 initial velocity of the second object (m/s)

 final velocity of the combined objects (m/s)

Answer 2

Answer:

When two objects collide under inelastic condition, the final velocity with which the object moves is given by-

V=(M1V1+M2V2)(M1+M2)

Where,

V= Final velocity

M1= mass of the first object in kgs

M2= mas of the second object in kgs

V1= initial velocity of the first object in m/s

V2= initial velocity of the second object in m/s
