Question

Two hockey players have a total momentum of +200 kg x m/s before a collision (+ is to the right). After the collision, they move together. In what direction do you have move and what is their Momentum?

Answer 1

Total momentum after the collision: +200 kg m/s to the right

Explanation:

We can answer this question by using the law of conservation of momentum, which states that for an isolated system (=no external forces acting on the system), the total momentum is conserved.

Mathematically,

$p_i=p_f$

where

$p_i$ is the total momentum before the collision

$p_f$ is the total momentum after the collision

In this problem, the system consists of two hockey players. Before the collision, their total momentum is

$p_i = +200 kg m/s$ (to the right)

Therefore, according to the law of conservation of momentum, their total momentum after the collision must be the same:

$p_f = +200 kg m/s$

And given that the sign is +, the direction is still the same, therefore to the right.
