So we explicitly have two different objects, if one moving to the east, and we'll call this object one, and one moving to the north, and we will call this object number two.
00:24
So the problem statement explicitly says that momentum is conserved, which implies that the initial momentum will equal the final momentum, regardless of any type of collision, assuming that there's no new external forces on the system.
00:42
So object 1 has a mass of 16 .2 kilograms and a velocity of 8 .56 meters per seconds.
01:04
In essentially, these are both in the x direction, a positive x direction, while mass 2 has a mass of 26 .5 kilograms with a velocity of 4 .66 meters per second.
01:32
So this is in the y direction for momentum, and this one is in the x direction for momentum.
01:40
So the trick part of this question, since you only have to calculate the magnitude of momentum before and after, the magnitude of momentum is the same before and after two.
01:51
To the conservation momentum.
01:53
So essentially, you only have to calculate the initial momentum and take essentially the square root of the components...
