Question

a bus decreases speed from 60 km/h to 30 km/h in 5 second. find the acceleration of the bus​

Answer 1

Answer:

In v-u/t will be used as there is no particular distance given

Explanation:

In v+u/t will be used as there is no particular distance given to us

so here u= 60

so here v = 30

t=5 second s

But here have to convert velocities to m/s so u= 50/3

v=25/3

t=5 seconds

so v-u/t

25/3-50/3/5

-25/3×5

-125/3

-41.6m/s retardation or acceleration of the bus.
