Answer:
10 kg.m/s
Explanation:
Momentum is a product of mass and velocity, expressed as p=mv where m is the mass of an object, v is the velocity of an object and p denote momentum.
The principle of linear momentum states that the sum of momentum before and after collision are always equal.
Given mass of initially as 2kg and its velocitu as 5kg and taking forward direction as positive.
Momentum before collision will be
P=2kg*5m/s=10 kg.m/s
