Question

a car travelling from 20kmphr up to 60kmphr in 6 sec what is its acceleration​

Answer 1

Explanation:

Step by step solutio..

= 20 km/h <br>

<br>

…(1) <br> Final speed,

= 60 km/h <br>

<br>

= 16.66 m/s

…(2) <br> Acceleration,

= ? (To be calculated) <br> And,

Time,

= 6 s <br> We know that :

<br> So,

16.66=5.55+

<br>

<br>

<br>

<br> Thus, Acceleration,

= 1.85 m/

Answer 2

Answer:

1.85 m/s2

Explanation:

u = initial speed

v= final

acceleration= a

time= t

now for u

20 km /h = 20*1000/60*60 = 5.55 m/s

now for v

60km/h = 60*1000/60*60 = 16.66 m/s

we know v= u+at

6a= 16.66- 5.55

a = 11.11/6

= 1.85m/s2
