Vector Addition

From a Japanese TV show - a real life example of adding vectors and relative motion. The truck is moving at 100km/hr and a ball is shot backwards at 100 km/hr, resulting in it coming to a complete ...

You're a retard.... the forward bouncing of the ball is generated by the spin of the throwing machine.

from the replay i think it may have just been "spin" from the ball, since it doesn't actually move in the direction of the truck until it bounces :)

The law of conservation of momentum just states that an object's momentum does not change unless acted upon by an outside force.

I think you have a fundamental misunderstanding of what momentum really is.

As other posters have stated, the ball's spin caused it to roll on the ground (which ironically enough, can be explained with something called angular momentum, which is also a conserved quantity in physics).

Can anyone tell me the name of this show? I've seen other outstanding clips (rolling a tire down a ski slope, how much weight in fish a stray cat can carry), and want to find more.
