Question

a car initially at rest picks up a velocity of 108 km/hr in 0.5 min calculate accelaration of car in S.I unit

Answer 1

Hlo friend.. Cutiepie Here..

Here is ur answer :

Initial velocity u = 0

Final velocity v = 108 km/h

We have to convert km / h into m/s

So we have to multiply it by 5 / 18

= 108 × 5/ 18 m/ s

[ 18 × 6 = 108]

= 6 × 5 m / s

= 30 m/s

Time t = 0.5 min

1 min = 60 sec

0.5 min = 30 sec


Acceleration of car

$= \frac{final \: \: velocity \: - \: \: inital \: \: velocity}{time}$



$= \frac{v - u}{t}$


$= \frac{30 - 0}{30}$


$= \frac{30}{30}$


$= 1$

Acceleration of car = 1 m/s²
