Question

A bus decreases it's speed from 80km/h to 60km/h in5 sec. Find the acceleration of the bus

Answer 1

Hii Friend

Good evening

Lets solve This problem

Q.Easy

Solution:

Given:

Initial velocity (u)=80km/h=(80×15/8)=150m/s

Final velocity(v)=60km/h=(60×15/8)=112.5m/s

Time taken(t)=5sec

FORMULA for acceleration(a)=v-u/t

a=112.5-150/5=-7.5

Hence,Answer =Acceleration=-7.5m/s2
