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)

Question

Responses

275 kg⋅m/s
275 kilograms times meters per second

55 kg⋅m/s
55 kilograms times meters per second

−55 kg⋅m/s
negative 55 kilograms times meters per second

−275 kg⋅m/s

Answer 1

To find the total momentum after the collision, we need to add up the momentums of all three objects.

Momentum of object 1: 110 kg⋅m/s
Momentum of object 2: -65 kg⋅m/s
Momentum of object 3: -100 kg⋅m/s

Total momentum = 110 kg⋅m/s + (-65 kg⋅m/s) + (-100 kg⋅m/s)
= 110 - 65 - 100 kg⋅m/s
= -55 kg⋅m/s

Therefore, the total momentum after the collision is -55 kg⋅m/s.
