In a collision, a 15 kg mass moving at 2m/s transfers all of its momentum to a 5kg mass. What is the velocity of the 5kg mass after collision?

Speed of 5 kg mass when momentum it transferred to it is 6 m/s

Explanation:

As we know that momentum is the product of mass and velocity of the object

So here we know that

now momentum of this object is given as

Now when it transfer all its momentum into the other object then we have

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
