Question

A bus decreases its speed from 80km/h to 60km/h in 5 seconds. Find out the retardation of the bus. full numerical solve with anawer​

Answer 1

$\huge\pink{Answer}$

☞Here we have, u=80 km/h,v=60 km/h,t=5s

Therefore acceleration,a=?

we know that v=u+at

✍60km/h=80km/h+a×5s

=60km/h-80km/h=a×5s

=-20km/h=a×5s

$a = - \frac{20km \div h}{5s}$

a= -4km/h/s

Therefore acceleration= -4km/h/s or = 1.1 m/s²
