Question

Pls solve question number 6

Answer 1

Heya!!

Abhiranjan raj presenting here....

_________________________

given,

initial velocity=60km/h
=60*5/18=16.66m/sec.

final velocity=80km/h
80*5/18=22.22m/s.
time=2 min

so, that,
time in second =2/60=0.033 sec

then,

acceleration = final - initial/time

a=22.22-16.66

a=5.56/0.033=16.9m/s^2

Hope it helps you

Answer 2

Hey mate!!!!!!

Here is your ans-_-_-_-_-_-_-_-_-

(10:52 - 10:50)=2 min
2/60=1/30

v= 80 km/h
u= 60 km/h
$a = \frac{v - u}{t} \\ a = \frac{80 - 60}{ \frac{1}{30} } \\ a = \frac{20}{ \frac{1}{30} } \\ a = 600$
Hence,a=600km/h²

Hope it help✌️✌️✌️✌️✌️
