Question

A car is moving with 30 m/s speed up to 40 m/s in 2 seconds. what is the acceleration of the car?​

Answer 1

Given :

A car is moving with 30 m/s speed up to 40 m/s in 2 seconds .

To Find :

Acceleration of the car .

Solution :

$\longmapsto\tt{Initial\:Velocity\:(u)=30\:m/s}$

$\longmapsto\tt{Final\:Velocity\:(v)=40\:m/s}$

$\longmapsto\tt{Time\:Taken\:(t)=2\:sec}$

Using Formula :

$\longmapsto\tt\boxed{Acceleration=\dfrac{v-u}{t}}$

Putting Values :

$\longmapsto\tt{\dfrac{40-30}{2}}$

$\longmapsto\tt{\dfrac{10}{2}}$

$\longmapsto\tt\bf{5\:{m/s}^{2}}$

So , The Acceleration of the car is 5 m/s² .

_____________________

Acceleration :

It is defined as the rate of change of velocity of the object .

Formula of Acceleration is :-

$\longrightarrow\tt{Acceleration=\dfrac{v-u}{t}}$

Here , in this question :

v = Final Velocity

u = Initial Velocity

t = time taken
