Achild slides down a hill on a toboggan with an acceleration of 1.8 m/s^2. if she starts at rest, how far has she traveled in : (a) 1.0 s, (b) 2.0 s, and (c) 3.0 s?

Explanation:

It is given that,

The acceleration of the toboggan,

Initial speed of the toboggan, u = 0

We need to find the distance covered by the toboggan. Using the second equation of motion as :

At t = 1 s

At t = 2 s

At t = 3 s

Hence, this is the required solution.

i. like it i'm gonna edit it tomorrow

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.
