Question

A bus decreases it's speed from 80 km h-1 to 60 km h-1 in 5 s . find the accelaration of the bus​

Answer 1

Answer:

-1.112 m/s

Step-by-step explanation:

Initial velocity of the bus, u= 80km/h= 80*5/18

= 22.22m/s

Final velocity of the bus, v= 60km/h= 60*5/18

= 16.66m/s

Time, t= 5s

Acceleration, a= (v-u)/t

= (16.66-22.22)/5

= -1.112 m/s

Hope it helps!
