A960 kg car initially moving at 30.0 m/s hits a 150-kg deer initially running at 12.0 m/s in the same direction. after the hitting. the deer remains on the car. what is the final velocity (in m/s)?

V = 27.56 m/s

Explanation:

It is given that,

Mass of the car,

Initial speed of the car,

Mass of the deer,    

Initial speed of the deer,

It is mentioned that after the hitting. the deer remains on the car. It is a case of inelastic collision. Let V is the speed of final speed of the deer and the car. Using the conservation of momentum to find it as :

V = 27.56 m/s

So, the final velocity of the deer and the car is 27.56 m/s.

are their multiple choices ?

explanation:

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.
