Answer:
The velocity of the players will be <u>2.88 m/s</u> in the <u>east</u> direction.
Explanation:
Let 'v' be the velocity of the players after collision.
Consider the east direction as positive direction.
Given:
Mass of the first player is,
kg
Initial velocity of the first player is,
m/s
Mass of the second player is,
kg
Initial velocity of the second player is,
m/s
In order to solve this problem we use the law of conservation of momentum which says that the total momentum must be conserved before and after the collision. So we can write:

Solving for v, we get:

Therefore, their velocity after the collision is 2.88 m/s.
The sign of the velocity after collision is positive. So, the players will move in the east direction only after collision.
Answer:
The question is incomplete. I will assume you intend to find the total momentum of the two carts during collision. Therefore, we can use the conservation of momentum principle to get the total momentum at a certain instant before collision.
Explanation:
The conservation of momentum principle states that the initial net momentum of two bodies before collision is equal to the final net momentum after collision.
In this case, let's denote the rolling cart as <em>'a'</em> and the stationary cart as <em>'b'</em>.


Therefore, the total momentum before collision is 11.02 Kg.m/s.
