Question 17 ListenA blue lab cart is traveling west on a track when it collides with and sticks to a red lab cart traveling east. The magnitude of the momentum of the blue cart before the collision is 2.0 kilogram • meters per second, and the magnitude of the momentum of the red cart before the collision is 3.0 kilogram • meters per second. The magnitude of the total momentum of the two carts after the collision is1.0 kg • m/s2.0 kg • m/s3.0 kg • m/s5.0 kg • m/s

Answer 1

option A

Step-by-step 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
