Ina shoots a large marble (marble a, mass: 0.08 kg) at a smaller marble (marble b, mass: 0.05 kg) that is sitting still. marble a was initially moving at a velocity of 0.5 m/s, but after the collision it has a velocity of –0.1 m/s. what is the resulting velocity of marble b after the collision?

the other ball will move with speed 0.96 m/s

Explanation:

Here in collision type of questions we can use momentum conservation because there is no force on the system

So here we will have

so here we have

So the light ball will move with speed 0.96 m/s

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.
