Momentum Problem: Two Objects Colliding (inelastic collision physics / dynamics)

In this video i discuss what happens when two cars of different mass and same speed but in opposite direction collide. I use the formula mass 1 x velocity 1 - mass 2 x velocity 2 = mass Total x Velocity Final. This equation will solve momentum problems when the objects are going in opposite directions. If you need any help with this concept feel free to ask in the comments below i check my YouTube account just about every day. If you like my style subscribe because more physics problems, answers, equations, and questions are coming.

thanks this was always confusing for me but this video cleared it up

I have a question.

The bighorn sheep can weigh up to 500 pounds. A bighorn ram can withstand a blow to the head 60 times greater than what it would take to fracture your own skull. When two of the rams collide in battle, they often do so at a combined speed of 70 mph. Multiplying that figure by the combined weight of the two animals, (1, 000 pounds) suggests an output of 4, 000 foot-pounds of energy.

Is that right?

P.S. Remember, 500 pounds is 227.2727273 kilograms, 1, 000 pounds is 454.5454545 kilograms and 70 mph is 112 kilometers an hour.

Thanks for that - will help my physics class.

@ Vitamins And Mercury - the formula you have used is not correct. It should be mass 1 x velocity 1 + mass 2 x velocity 2 = mass Total x Velocity Final. You working is correct as velocity2 is negative (moving in the negative direction). Anyway, thanks for the good attempt.
A general comment: Momentum remains conserved in case of any collision (elastic or inelastic). So total momentum before the collision = total momentum after the collision. For this problem, use this formula keeping the directions in mind.

If I strike a piano key, why does the key initially move faster than my finger before reestablishing contact?

I need an equation for two objects moving in the same direction, but the one behind the other is going faster, I need the equation that tells me how long it will take them to hit. (Particle A starts with a velocity of 11.2m/s and an accelleration of 4.3m/s2. Particle B gets a head start of 35m, initially going at 6.1m/s and accelerates at 3.9m/s2. When do the particles meet

How do we find the direction after the collision

[squidaker]

I'm most likely the only one here out of pure curiosity and not cause I have a test.😂

[henryshingalili]

imagine watching that.. had your video been just a little longer.. besides "the formula"

[karlmarst]

Sir I want to use this small clip of this video in my project under fair use in you tube so please give me permission to use it

[Zero_Dollar]

can you please help me on that
i have two cars on opposite direction
i want to calculate the other car speed as i know the distance between two cars using laser sensor but i coundn't find the right formula to calculate the speed of other car

[Mvingtargetz]

I wonder what would happen if they both weighed the same, going at the same speed and at the exact same point of impact exactly head one with one another.

[tzebieliuyi]

what happens if 2 cars with the same momentum collide together?

And how about a 3-ton bison charging at 40 mph?

P.S. Remember, 3 tons is 6, 000 pounds which is 2, 727.272727 kilograms and 40 mph is 64 kilometers and hour.

[benmuns]

And how about a 1-ton musk ox charging at 40 mph?

P.S. Remember, 1 ton is 2, 000 pounds which is 909.0909091 kilograms and 40 mph is 64 kilometers an hour.

[antushdass]

Can someone please make me understand how is the final velocity

[mxo]

You can't get the correct answer for momentum if don't convert km/h to m/s

[HornbyCrazy]

I can't understand make this so a 10 year old could understand
