How do you find the velocity of two objects after a collision?

If two particles are involved in an elastic collision, the velocity of the second particle after collision can be expressed as: v2f=2⋅m1(m2+m1)v1i+(m2−m1)(m2+m1)v2i v 2 f = 2 ⋅ m 1 ( m 2 + m 1 ) v 1 i + ( m 2 − m 1 ) ( m 2 + m 1 ) v 2 i .

What is the final velocity of the combined objects?

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.

What happens when two objects of equal mass collide?

In a collision, there is a force on both objects that causes an acceleration of both objects; the forces are equal in magnitude and opposite in direction. For collisions between equal-mass objects, each object experiences the same acceleration.

How do you find final velocities in an elastic collision?

v2f = final velocity of second object. The initial momentum of the system (M) is equal to m1*v1i + m2*v2i. By conservation of momentum, the final momentum of the system, m1*v1f + m2*v2f, is also equal to M. So, m1*v1i + m2*v2i = m1*v1f + m2*v2f.

What happens when two objects with the same mass and velocity collide?

When two objects with the same mass collide, Newton’s laws tell us that they will accelerate the same amount but in opposite directions. Recall that force, velocity, and acceleration have both magnitude and direction. We use positive and negative signs to indicate the direction of each of these quantities.
