Question

A car accelerates from 4 meters/second to 16 meters/second in 4 seconds. The car’s acceleration is__________ meters/second. Can some help. PLEASE . HAPPY THANKSGIVING!

Answer 1

here is your answer

I hope it will help u

Answer 2

$hey \: mate \: here \: is \: ur \: answer \:$

GIVEN THAT ➡️A car accelerates from 4 meters / second to 16 meters / second in 4second We need to find

the cars Acceleration.


SOLUTION ➡️ According to Question it's given that ⬇️



Initial velocity (U) of car = 4m/s. [ initial velocity is velocity that an object have in initial or starting According

to frame of reference]


NOW Similarly it's given that


Final velocity (v) of car = 16 m/ s [ Now final velocity of an object is the velocity of object at the end of

reference ]


SO NOW TO FIND ACCELERATION


We know that


Acceleration is equal to change of velocity during a time period .

Therefore formula for finding Acceleration is


$\frac{v - u}{t} \: ( \: where \: (v) \: is \: final \: velocity \: \: and \: (u) \: is \: initial \: velocity \: )$
$( \: and \: t \: is \: time \: )$

SO Here

Time ( t) is =. 4 seconds


Now putting the values of (V) (U) and (t ) in above Acceleration formula we have


$\frac{16 - 4}{4s}$

THAT IS

$\frac{12m \: per \sec}{ \: 4sec}$

SO WE HAVE


$acceleration \: = \: 3 \: m \: per \: {s}^{2}$


HENCE THE REQUIRED ANSWER IS

$3 \: meter \: per \: second \: square$


$hope \: its \: helpful \:$
