Arunner at a speed of 3.5 m/s comes to a stop in 0.15 seconds. what is the deceleration?

Deceleration of the runner is -23.33

Given:

Initial velocity = 3.5

Final velocity = 0

Time = 0.15 s

To find:

Deceleration of runner = ?

Formula used:

According to first equation of motion,

v = u + at

Where, v = final velocity

u = initial velocity

a = deceleration

t = time

Solution:

According to first equation of motion,

v = u + at

Where, v = final velocity

u = initial velocity

a = deceleration

t = time

0 = 3.5 + a (0.15)

-3.5 = 0.15 (a)

a =

a = -23.33

Negative sign shows that it is deceleration.

Thus, deceleration of the runner is -23.33

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

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.
