Answer 1

Answer:

A bus decreases its speed from 90km/hr to 54km/hr in 5 seconds. Find the accleration

Answer 2

QUESTION:-

. A bus decreases its speed from 90 km/hr to 54 km/hr in 4 second. Find the acceleration of the bus.​

EXPLNATION:-

=>Initial velocity=90 km/hr=25 m/s

=>Final velocity=54 km/hr=15 m/s

=>Time=4 s

We know,

a=v-u/t

Where a=acceleration

v=final velocity

u=initial velocity

t=times taken

Let's calculate

a=(15-25)/4

a=-10/4

a=-2.5 m/s²

So the acceleration is -2.5 m/s²
