Kale · Answer 1

option A

Explanation:

given,

momentum of blue car in west direction = Pa = 2 kg. m/s

momentum of red cart in east direction = Pb = 3 kg. m/s

total momentum of the two cart = ?

Pa = 2 Kg. m/s

Pb = - 3 kg. m/s

Total momentum

P = Pa + Pb

P = 2 - 3

P = - 1 kg. m/s

hence, the total momentum of the two carts after the collision is 1.0 kg•m/s

The correct answer is option A
