Question

Sayid made a chart listing data of two colliding objects.

According to the law of conservation of momentum, what is the missing value in the chart?

Answer 1

The missing value is 6 m/s

Step-by-step explanation:

Hope this helps :))

Answer 2

velocity of combined objects is 6 m/s

Step-by-step explanation:

As per law of conservation of momentum

total momentum before collision = total momentum after collision

since the two objects sticks together after collision so we will have

`m_1v_(1i) + m_2v_(2i) = (m_1 + m_2) v`

Now plug in all values in it

`300(10) + 100(-6) = (300 + 100) v`

`3000 - 600 = 400(v)`

`2400 = 400 v`

`v = 6 m/s`

so the missing value in the table is velocity which is 6 m/s
