For some context, completed a lab in my physics class and we did three different trials, an explosion, inelastic, and elastic trial with a red and blue car, I have listed their velocities at certain points. Each velocity Is in m/s

Explosion

Velocity red: 0.745

Velocity blue: 0.705

Inelastic

Velocity red before 0.821

Velocity red after 0.388

Final velocity red and blue after collision: 0.388

Elastic

Velocity red before 0.588

Velocity red after 0.550

Final velocity blue 0.572

1. Calculate the initial and the final momentum for each cart for each of the collisions.

1. Calculate the percent difference between the total initial momentum and the total final momentum for each collision.

%difference= (Pbefore-Pafter/Pbefore) x 100

1. Calculate the initial and the final kinetic energy for each cart for each of the collisions.

1. Calculate the percent of the total kinetic energy lost for each collision.

%KE lost= ( KEbefore-KEafter/KEbefore) x 100

In general, what did you learn about conservation of momentum and kinetic energy in different types of collisions?

1. Was momentum conserved for all types of collisions?

1. Was total velocity conserved for all types collisions?

1. Was energy conserved for all types of collisions? Where did the extra kinetic energy come from in the explosions? What happens to the initial kinetic energy that is lost in a collision?
