Problem 8 .1, we have a 10 ,000 kilogram truck, which is moving at 12 meters per second, and the first thing we're asked about is what is the momentum of this.
00:12
So we know that the momentum, the magnitude of the momentum is the mass times the speed.
00:25
And so this works out to be 120 ,000 kilogram meters per second.
00:39
Now, b has two parts.
00:40
In the first part, we have a 2 ,000 kilogram suv, and we want the momentum to be equal.
01:05
And so what is the speed at which this happens? well, you can see from here that v is going to be p over m, and this works out to give you 60 meters per second in order to have the same momentum...
