Acar traveling at 37m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration

Answer

The acceleration is

to the nearest tenth

Explanation

Since the car was travelling at before it starts to decelerate, the initial velocity is

.

The final velocity is , because the car came to a stop.

The time taken is .

Using the Newton's equation of linear motion,

, we find the acceleration by substituting the known values.

This implies that,

This gives us,

We divide both sides by 15 to get,

or

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.
