A 3.70 kg block moving 2.09 m/s right hits a 2.42 kg block moving 3.92 m/s left. Find the total momentum of the system.

-1.7534 Kg. m/s

Explanation:

Momentum, p is a product of mass and velocity, expressed as p = mv where m is the mass and v is the velocity which is dependent on the direction. Taking left as negative and right as positive then the initial momentum will be

p=-2.42*3.92 + (3.7*2.09) = -1.7534 Kg. m/s
