Usain Bolt, an Olympian from Jamaica, is the fastest human ever recorded. Determine his average rate of acceleration if he achieved a speed of 10.4 m/s in 9.58 sec. (Think about what a sprinter's initial speed is.)

1.09 m/s²

Explanation:

Given:

Final speed of the sprinter (v) = 10.4 m/s

Initial speed of the sprinter (u) = 0 m/s (As the sprinter starts from rest position)

Time taken to reach the speed(Δt) = 9.58 s

Average acceleration is defined as the rate of change of velocity.

So, the acceleration of the sprinter is given as:

Plug in all the given values and solve for acceleration, 'a'. This gives,

Therefore, the magnitude of the average acceleration of the sprinter is 1.09 m/s².

d

explanation:

v=uf/(u-f)

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.
