Answer:
Explanation:
We must use conservation of linear momentum before and after the collision,
Before the collision we have:
where these are the masses are initial velocities of both players.
After the collision we have:
since they clong together, acting as one body.
This means we have:
Or:
Which for our values is:
Velocity is the vector,
made up of the scalar speed + direction of speed
b). Displacement is the vector,
made up of the scalar distance + direction of distance
