Can someone check this answer for me?

Two ice hockey players are moving towards each other.

Player 1 has a mass of 78kg and a velocity of 7.5 m/s

Player 2 has a mass of 91kg and a velocity of -5.5m/s

During the collision, total momentum of the players is conserved.

Immediately after the collision, the players move together towards the right

Calculate the velocity of the players after the collision.

My working out is

Momentum of player 1 = 78×7.5=585

Momentum of player 2= 91x-5.5=-500.5

Total momentum before event= 585+-500.5 = 84.5

momentum before (84.5) = momentum after (also 84.5)

84.5 = velocity x the two players total mass

84.5 = velocity x (78+91)

84.5 / 169 = 0.5m/s

So their velocity is 0.5m/s as they move to the right.

Can someone tell me if this is correct?

its correct

My working out is

Momentum of player 1 = 78×7.5=585

Momentum of player 2= 91x-5.5=-500.5

Total momentum before event= 585+-500.5 = 84.5

momentum before (84.5) = momentum after (also 84.5)

84.5 = velocity x the two players total mass

84.5 = velocity x (78+91)

84.5 / 169 = 0.5m/s

it moves to the right
