Question

a bus decreases its speed from 80 kilometre per hour to 60 kilometre in 5 seconds find acceleration
​

Answer 1

Answer:

-1.11 m s^-2

Step-by-step explanation:

first convert the initial and final velocity to m/s.

By multiplying with 5/18

then apply the formula

a = (v-u)/t

Answer 2

AnswerInitial velocity u = 80 km h-1
