Answer:
Explanation:
For this problem, we just need to remember conservation of momentum, as there are no external forces in the horizontal direction:
where the suffix i means initial, and the suffix f means final.
The initial momentum will be:
as the second puck is initially at rest:
Using the unit vector pointing in the original line of motion:
So:
Knowing the magnitude and directions relative to the x axis, we can find Cartesian representation of the vectors using the formula
So, our velocity vectors will be:
We got
So, we got the equations:
and
.
From the last one, we get:
and, for the first one:
so:
and
