Question

In a closed system, three objects have the following momentums: 110 kg⋅m/s
, −65 kg⋅m/s
, and −100 kg⋅m/s
. The objects collide and move together. What is the total momentum after the collision?(1 point)
Responses

55 kg⋅m/s

55 kilograms times meters per second

275 kg⋅m/s

275 kilograms times meters per second

−55 kg⋅m/s

negative 55 kilograms times meters per second

−275 kg⋅m/s

negative 275 kilograms times meters per second

Answer 1

Total momentum = 110 + (−65) + (−100) = −55 kg·m/s.

So the correct choice is −55 kg⋅m/s.
